DIFFERENCES BETWEEN PD17236 AND PD17P236 PD17P236 is equipped with PROM to which data can be written by the user instead of the internal mask ROM (program memory) of the PD17236. Table 1-1 shows the differences between the PD17236 and PD17P236. The CPU functions and internal hardware of the PD17P236, 17230, 17231, 17232, 17233, 17234, 17235, and 17236 are identical. Therefore, the PD17P236 can be used to evaluate the program developed for the PD17230, 17231, 17232, 17233, 17234, 17235, and 17236 system. Note, however, that some of the electrical specifications such as supply current and low-voltage detection voltage of the PD17P236 are different from those of the PD17230, 17231, 17232, 17233, 17234, 17235, and 17236.

PIN FUNCTIONS, the RESET pin also has the function of setting a test mode (for IC testing) in which the internal operations of the PD17P236 are tested. When a voltage higher than VDD is applied to either of these pins, the test mode is set. This means that, even during normal operation, the PD17P236 may be set in the test mode if noise exceeding VDD is applied. For example, if the wiring length of the RESET or INT pin is too long, noise superimposed on the wiring line of the pin may cause the above problem. Therefore, keep the wiring length of these pins as short as possible to suppress the noise; otherwise, take noise preventive measures as shown below by using external components. * Connect diode with low VF between VDD and RESET/INT pin VDD * Connect capacitor between VDD and RESET/INT pin VDD Diode with low VF RESET, INT VDD RESET, INT VDD 12 Data Sheet U14776EJ1V0DS00 PD17P236 3. WRITING AND VERIFYING ONE-TIME PROM (PROGRAM MEMORY) The program memory of the PD17P236 is a one-time PROM of 16,384 x 16 bits. To write or verify this one-time PROM, the pins shown in Table 3-1 are used. Note that no address input pin is used. Instead, the address is updated by using the clock input from the CLK pin. Table 3-1. Pins Used to Write/Verify Program Memory Pin Name VPP VDD CLK MD0-MD3 D0-D7 Function Supplies voltage when writing/verifying program memory. Apply +12.5 V to this pin. Power supply. Supply +6 V to this pin when writing/verifying program memory. Inputs clock to update address when writing/verifying program memory. By inputting pulse four times to CLK pin, address of program memory is updated. Input to select operation mode when writing/verifying program memory. Inputs/outputs 8-bit data when writing/verifying program memory. 3.1 Operating Mode When Writing/Verifying Program Memory The PD17P236 is set in the program memory write/verify mode when +6 V is applied to the VDD pin and +12.5 V is applied to the VPP pin after the PD17P236 has been in the reset status (VDD = 5 V, RESET = 0 V) for a specific time. In this mode, the operating modes shown in Table 3-2 can be set by setting the MD0 through MD3 pins. Leave all the pins other than those shown in Table 3-1 unconnected or connect them to GND via pull-down resistor (470 ). (See PIN CONFIGURATION (2) PROM programming mode.) Table 3-2.

Caution To use a system clock oscillator circuit, perform the wiring in the area enclosed by the dotted line in the above figure as follows, to avoid adverse wiring capacitance influences: * Keep wiring length as short as possible. * Do not cross a signal line with some other signal lines. Do not route the wiring in the vicinity of lines through which a large current flows. * Always keep the oscillator capacitor ground at the same potential as GND. Do not ground the capacitor to a ground pattern, through which a large current flows. * Do not extract signals from the oscillator.

DEVELOPMENT TOOLS To develop the programs for the PD17P236 subseries, the following development tools are available: Hardware Name In-circuit emulator IE-17K, IE-17K-ETNote 1 Remarks IE-17K and IE-17K-ET are the in-circuit emulators used in common with the 17K series microcontroller. IE-17K and IE-17K-ET are connected to a PC-9800 series or IBM PC/ATTM compatible machines as the host machine with RS-232C. By using these in-circuit emulators with a system evaluation board corresponding to the microcomputer, the emulators can emulate the microcomputer. A higher level debugging environment can be provided by using man-machine interface SIMPLEHOST TM. This is an SE board for PD17236 subseries. It can be used alone to evaluate a system or in combination with an in-circuit emulator for debugging. EP-17K28GT is an emulation probe for 17K series 28-pin SOP (GM-375B). When used with Note 2 EV9500GT-28 , it connects an SE board to the target system. EP-17K30GS is an emulation probe for 17K series 30-pin SSOP (MC-5A4). When used with EV-9500GT-30Note 3, it connects an SE board to the target system. The EV-9500GT-28 is a conversion adapter for the 28-pin SOP (GM-375B). It is used to connect the EP-17K28GT and target system. The EV-9500GT-30 is a conversion adapter for the 30-pin SSOP (MC-5A4). It is used to ) connect the EP-17K30GS and target system. AF-9706, AF-9708, and AF-9709 are PROM programmers corresponding to PD17P236. By connecting program adapter PA-17P236 to this PROM programmer, PD17P236 can be programmed. PA-17P236 are adapters that is used to program PD17P236, and is used in combination with AF-9706, AF-9708, or AF-9709.

Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.
