Active at 5 MHz (AT27C010) JEDEC Standard Packages 32-Lead 600-mil PDIP 32-Lead PLCC 32-Lead TSOP 5V 10% Supply High Reliability CMOS Technology 2000V ESD Protection 200 mA Latchup Immunity RapidTM Programming Algorithm - 100 s/byte (typical) CMOS and TTL Compatible Inputs and Outputs Integrated Product Identification Code Commercial and Industrial Temperature Ranges 1 Megabit (128K x 8) OTP CMOS EPROM Description The AT27C010/L is a low-power, high performance 1,048,576 bit one-time programmable read only memory (OTP EPROM) organized as 128K by 8 bits. They require only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 45 ns, eliminating the need for speed reducing WAIT states on high performance microprocessor systems. Two power versions are offered. In read mode, the AT27C010 typically consumes 25 mA while the AT27C010L requires only 8 mA. Standby mode supply current for both parts is typically less than 10 A.

All devices feature two line control (CE, OE) to give designers the flexibility to prevent bus contention. With 128K byte storage capability, the AT27C010/L allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. Atmel's 27C010/L have additional features to ensure high quality and efficient production use. The RapidTM Programming Algorithm reduces the time required to program the part and guarantees reliable programming. Programming time is typically only 100 s/byte. The Integrated Product Identification Code electronically identifies the device and manufacturer. This feature is used by industry standard programming equipment to select the proper programming algorithms and voltages. System Considerations Switching between active and standby conditions via the Chip Enable pin may produce transient voltage excursions. Unless accommodated by the system design, these transients may exceed data sheet limits, resulting in device non-conformance. At a minimum, a 0.1 F high frequency, low inherent inductance, ceramic capacitor should be utilized for each device. This capacitor should be connected between the VCC and Ground terminals of the device, as close to the device as possible. Additionally, to stabilize the supply voltage level on printed circuit boards with large EPROM arrays, a 4.7 F bulk electrolytic capacitor should be utilized, again connected between the VCC and Ground terminals. This capacitor should be positioned as close as possible to the point where the power supply is connected to the array. 3-154 AT27C010/L AT27C010/L Block Diagram Absolute Maximum Ratings* Temperature Under Bias ................ -55C to +125C Storage Temperature...................... -65C to +150C Voltage on Any Pin with Respect to Ground......................... -2.0V to +7.0V (1) Voltage on A9 with Respect to Ground ...................... -2.0V to +14.0V (1) VPP Supply Voltage with Respect to Ground....................... -2.0V to +14.0V (1) *NOTICE: Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.

The address is set to the first location. VCC is raised to 6.5V and VPP is raised to 13.0V. Each address is first programmed with one 100 s PGM pulse without verification. Then a verification / reprogramming loop is executed for each address. In the event a byte fails to pass verification, up to 10 successive 100 s pulses are applied with a verification after each pulse. If the byte fails to verify after 10 pulses have been applied, the part is considered failed. After the byte verifies properly, the next address is selected until all have been checked. VPP is then lowered to 5.0V and VCC to 5.0V. All bytes are read again and compared with the original data to determine if the device passes or fails. tAS tCES tDS tAH tDH tDFP tVPS tVCS tPW tOE tPRT Address Setup Time CE Setup Time 2 2 2 2 0 2 0 2 2 (3) tOES OE Setup Time Data Setup Time Address Hold Time Data Hold Time OE High to Output Float Delay (2) VPP Setup Time VCC Setup Time PGM Program Pulse Width Data Valid from OE VPP Pulse Rise TIme During Programming 130 ns s s 95 105 150 s ns ns 50 *AC Conditions of Test: Input Rise and Fall Times (10% to 90%)..........20 ns Input Pulse Levels...............................0.45V to 2.4V Input Timing Reference Level...............0.8V to 2.0V Output Timing Reference Level............0.8V to 2.0V Notes: 1.
