GENERAL DESCRIPTION
The ISD4004 ChipCorder(R) Products provide highquality, 3-volt, single-chip record/playback solutions for 8- to 16-minute messaging applications which are ideal for cellular phones and other portable products. The CMOS-based devices include an on-chip oscillator, antialiasing filter, smoothing filter, AutoMuteTM feature, audio amplifier, and high density, multilevel Flash storage array. The ISD4004 series is designed to be used in a microprocessor- or microcontroller-based system. Address and control are accomplished through a Serial Peripheral Interface (SPI) or Microwire Serial Interface to minimize pin count. Recordings are stored in on-chip nonvolatile memory cells, providing zero-power message storage. This unique, single-chip solution is made possible through ISD's patented multilevel storage technology. Voice and audio signals are stored directly into memory in their natural form, providing high-quality, solid-state voice reproduction.

ISD4004 Series
DETAILED DESCRIPTION
SPEECH/SOUND QUALITY
The ISD4004 ChipCorder series includes devices offered at 4.0, 5.3, 6.4, and 8.0 KHz sampling frequencies, allowing the user a choice of speech quality options. Increasing the duration within a product series decreases the sampling frequency and bandwidth, which affects sound quality. Please refer to the ISD4004 Series Product Summary table on the second page to compare filter pass band and product durations. The speech samples are stored directly into on-chip nonvolatile memory without the digitization and compression associated with other solutions. Direct analog storage provides a natural sounding reproduction of voice, music, tones, and sound effects not available with most solid-state solutions.
PROGRAMMING
The ISD4004 series is also ideal for playback-only applications, where single or multiple message Playback is controlled through the SPI port. Once the desired message configuration is created, duplicates can easily be generated via an ISD programmer.
PIN DESCRIPTIONS
VOLTAGE INPUTS (VCCA, VCCD)
To minimize noise, the analog and digital circuits in the ISD4004 devices use separate power busses. These +3 V busses are brought out to separate pins and should be tied together as close to the supply as possible. In addition, these supplies should be decoupled as close to the package as possible.
DURATION
To meet end system requirements, the ISD4004 series products are single-chip solutions at 8, 10, 12, 16 minutes.
GROUND INPUTS (VSSA, VSSD)
The ISD4004 series utilizes separate analog and digital ground busses. The analog ground (VSSA) pins should be tied together as close to the package as possible and connected through a lowimpedance path to power supply ground. The digital ground (VSSD) pin should be connected through a separate low-impedance path to power supply ground. These ground paths should be large enough to ensure that the impedance between the VSSA pins and the VSSD pin is less than 3 W. The backside of the die is connected to VSS through the substrate resistance. In a chip-onboard design, the die attach area must be connected to VSS or left floating.
FLASH STORAGE
One of the benefits of ISD's ChipCorder technology is the use of on-chip nonvolatile memory, which provides zero-power message storage. The message is retained for up to 100 years (typically) without power. In addition, the device can be re-recorded (typically) over 100,000 times.
MICROCONTROLLER INTERFACE
A four-wire (SCLK, MOSI, MISO, SS) SPI interface is provided for ISD4004 control and addressing functions. The ISD4004 is configured to operate as a peripheral slave device, with a microcontrollerbased SPI bus interface. Read/Write access to all the internal registers occurs through this SPI interface. An interrupt signal (INT) and internal readonly Status Register are provided for handshake purposes.

ISD4004 Series NON-INVERTING ANALOG INPUT (ANA IN+)
This pin is the non-inverting analog input that transfers the signal to the device for recording. The analog input amplifier can be driven single ended or differentially. In the single-ended input mode, a 32 mVp-p (peak-to-peak) maximum signal should be capacitively connected to this pin for optimal signal quality. This capacitor value, together with the 3 KW input impedance of ANA IN+, is selected to give cutoff at the low frequency end of the voice passband. In the differential-input mode, the maximum input signal at ANA IN+ should be 16 mVp-p for optimal signal quality. The circuit connections for the two modes are shown in Figure 2 on page 2.
SLAVE SELECT (SS)
This input, when LOW, will select the ISD4004 device.
MASTER OUT SLAVE IN (MOSI)
This is the serial input to the ISD4004 device. The master microcontroller places data on the MOSI line one half-cycle before the rising clock edge to be clocked in by the ISD4004 device.
MASTER IN SLAVE OUT (MISO)
This is the serial output of the ISD4004 device. This output goes into a high-impedance state if the device is not selected.
INVERTING ANALOG INPUT (ANA IN-)
This pin is the inverting analog input that transfers the signal to the device for recording in the differential-input mode. In this differential-input mode, a 16 mVp-p maximum input signal at ANA IN- should be capacitively coupled to this pin for optimal signal quality as shown in the ISD4004 Series ANA IN Modes, Figure 2. This capacitor value should be equal to the coupling capacitor used on the ANA IN+ pin. The input impedance at ANA IN- is nominally 56 KW. In the single-ended mode, ANA IN- should be capacitively coupled to VSSA through a capacitor equal to that used on the ANA IN+ input.
SERIAL CLOCK (SCLK)
This is the clock input to the ISD4004. It is generated by the master device (microcontroller) and is used to synchronize data transfers in and out of the device through the MISO and MOSI lines. Data is latched into the ISD4004 on the rising edge of SCLK and shifted out of the device on the falling edge of SCLK.
INTERRUPT (INT)
The ISD4004 interrupt pin goes LOW and stays LOW when an Overflow (OVF) or End of Message (EOM) marker is detected. This is an open drain output pin. Each operation that ends in an EOM or Overflow will generate an interrupt including the message cueing cycles. The interrupt will be cleared the next time an SPI cycle is initiated. The interrupt status can be read by an RINT instruction. Overflow Flag (OVF)--The Overflow flag indicates that the end of the ISD4004's analog memory has been reached during a record or playback operation. End of Message (EOM)--The End-of-Message flag is set only during playback operation when an EOM is found. There are eight EOM flag position options per row.
AUDIO OUTPUT (AUD OUT)
This pin provides the audio output to the user. It is capable of driving a 5 KW impedance. It is recommended that this pin be AC coupled.
NOTE
The AUDOUT pin is always at 1.2 volts when the device is powered up. When in playback, the output buffer connected to this pin can drive a load as small as 5 KW. When in record, a resistor connects AUDOUT to the internal 1.2 volt analog ground supply. This resistor is approximately 850 KW, but will vary somewhat according to the sample rate of the device. This relatively high impedance allows this pin to be connected to an audio bus without loading it down.

ISD4004 Series ROW ADDRESS CLOCK (RAC)
This is an open drain output pin that provides a signal with a 200 ms period at the 8 KHz sampling frequency. (This represents a single row of memory and there are 2400 rows of memory in the ISD4004 series devices.) This signal stays HIGH for 175 ms and stays LOW for 25 ms when it reaches the end of a row. Table 1: External Clock Input Clocking Table
Sample Rate 8.0 KHz 6.4 KHz 5.3 KHz 4.0 KHz Required Clock 1024 KHz 819.2 KHz 682.7 KHz 512 KHz
Part Number ISD4004-08M ISD4004-10M ISD4004-12M ISD4004-16M
The RAC pin stays HIGH for 109.38 msec and stays LOW for 15.63 msec in Message Cueing mode (see page 5 for a more detailed description of Message Cueing). Refer to the AC Parameters table for RAC timing information on other sample rate products. When a record command is first initiated, the RAC pin remains HIGH for an extra TRACLO period. This is due to the need to load sample and hold circuits internal to the device. This pin can be used for message management techniques.
These recommended clock rates should not be varied because the antialiasing and smoothing filters are fixed. Thus, aliasing problems can occur if the sample rate differs from the one recommended. The duty cycle on the input clock is not critical, as the clock is immediately divided by two internally. If the XCLK is not used, this input should be connected to ground.
AUTOMUTETM FEATURE (AM CAP)
This pin is used in controlling the AutoMute feature. The AutoMute feature attenuates the signal when it drops below an internally set threshold. This helps to eliminate noise (with 6 dB of attenuation) when there is no signal (i.e., during periods of silence). A 1 mF capacitor to ground should be connected to the AM CAP pin. This capacitor becomes a part of an internal peak detector which senses the signal amplitude (peak). This peak level is compared to an internally set threshold to determine the AutoMute trip point. For large signals the AutoMute attenuation is set to 0 dB while 6 dB of attenuation occurs for silence. The 1 mF capacitor also affects the rate at which the AutoMute feature changes with the signal amplitude (or the attack time). The Automute feature can be disabled by connecting the AM CAP pin to VCCA.
EXTERNAL CLOCK INPUT (XCLK)
The external clock input for the ISD4004 products has an internal pull-down device. These products are configured at the factory with an internal sampling clock frequency centered to 1 percent of specification. The frequency is then maintained to a variation over the entire commercial temperature and operating voltage ranges as defined by the minimum/maximum limits in the applicable AC Parameters table. The internal clock has a tolerance, over the extended temperature, industrial temperature and voltage ranges as defined by the minimum/maximum limits in the applicable AC Parameters table. A regulated power supply is recommended for industrial temperature range parts. If greater precision is required, the device can be clocked through the XCLK pin in Table 1.

ISD4004 Series
SERIAL PERIPHERAL INTERFACE (SPI) DESCRIPTION
The ISD4004 series operates from an SPI serial interface. The SPI interface operates with the following protocol. The data transfer protocol assumes that the microcontroller's SPI shift registers are clocked on the falling edge of the SCLK. With the ISD4004, data is clocked in on the MOSI pin on the rising clock edge. Data is clocked out on the MISO pin on the falling clock edge. 1. All serial data transfers begin with the falling edge of SS pin. 2. SS is held LOW during all serial communications and held HIGH between instructions. 3. Data is clocked in on the rising clock edge and data is clocked out on the falling clock edge. 4. Play and Record operations are initiated by enabling the device by asserting the SS pin LOW, shifting in an opcode and an address field to the ISD4004 device (refer to the Opcode Summary on the page 6). 5. The opcodes and address fields are as follows: <8 control bits> and <16 address bits>. 6. Each operation that ends in an EOM or Overflow will generate an interrupt, including the Message Cueing cycles. The Interrupt will be cleared the next time an SPI cycle is initiated. 7. As Interrupt data is shifted out of the ISD4004 MISO pin, control and address data is simultaneously being shifted into the MOSI pin. Care should be taken such that the data shifted in is compatible with current system operation. It is possible to read interrupt data and start a new operation within the same SPI cycle. 8. An operation begins with the RUN bit set and ends with the RUN bit reset. 9. All operations begin with the rising edge of SS.
MESSAGE CUEING
Message cueing allows the user to skip through messages, without knowing the actual physical location of the message. This operation is used during playback. In this mode, the messages are skipped 1600 times faster than in normal playback mode. It will stop when an EOM marker is reached. Then, the internal address counter will point to the next message.

2. As the Interrupt data is shifted out of the ISD4004, control and address data is being shifted in. Care should be taken such that the data shifted in is compatible with current system operation. It is possible to read interrupt data and start a new operation at the same time. See Figure 5 through Figure 8 for Opcode format.

Message Cueing can be selected only at the beginning of a play operation.
POWER-UP SEQUENCE
The ISD4004 will be ready for an operation after TPUD (25 ms approximately for 8 KHz sample rate). The user needs to wait TPUD before issuing an operational command. For example, to play from address 00 the following programing cycle should be used. Playback Mode 1. 2. 3. 4. Send POWERUP command. Wait TPUD (power-up delay). Send SETPLAY command with address 00. Send PLAY command. 5. Send REC command. The device will start recording at address 00 and it will generate an interrupt when an overflow is reached (end of memory array). It will then stop recording. Record Mode 1. Send POWERUP command. 2. Wait TPUD (power-up delay). 3. Send POWERUP command. 4. Send SETREC command with address 00.
The device will start playback at address 00 and it will generate an interrupt when an EOM is reached. It will then stop playback.

Typical values: TA = 25C and 3.0 V. All min/max limits are guaranteed by ISD via electrical testing or characterization. Not all specifications are 100 percent tested. 3. Low-frequency cut off depends upon the value of external capacitors (see Pin Descriptions). 4. Single-ended input mode. In the differential input mode, VIN maximum for ANA IN+ and ANA IN- is 16mVp-p. 5. Sampling Frequency can vary as much as 2.25 percent over the commercial temperature, and voltage ranges, and -6/+4 percent over the extended temperature, industrial temperature and voltage ranges. For greater stability, an external clock can be utilized (see Pin Descriptions). 6. Playback and Record Duration can vary as much as 2.25 percent over the commercial temperature and voltage ranges, and -6/+4 percent over the extended temperature, industrial temperature and voltage ranges. For greater stability, an external clock can be utilized (see Pin Descriptions). 7. Filter specification applies to the antialiasing filter and the smoothing filter. Therefore, from input to output, expect a 6dB drop by nature of passing through both filters. 8. The typical output voltage will be approximately 570mVp-p with VIN at 32mVp-p. 9. For optimal signal quality, this maximum limit is recommended. 10. When a record command is sent, TRAC = TRAC + TRACLO on the first row addressed.
