UPD78F9188

NEW INFORMATION µPD78F9189/9188CT 8-BIT SINGLE-CHIP MICROCONTROLLER MOS INTEGRATED CIRCUIT The µPD78F9189 is NEW Subseries (small, general-purpose) in the 78K/0S Series. The µPD78F9189 replaces the internal ROM of the µPD789188 with flash memory. Because flash memory allows the program to be written and erased electrically with the device mounted on the board, this product is ideal for the evolution stages of system development, small-scale production and rapid development of new products. Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before designing. µPD789167, 789177, 789167Y, 789177Y Subseries User’s Manual: U14186E 78K/0S Series User's Manual Instruction: U11047E FEATURES • • • • • • • Pin compatible with mask ROM version (except VPP pin) Flash memory: 24 Kbytes ,Masked Version:16 Kbytes High-speed RAM: 512 bytes High-speed (0.4 µs: @5.0-MHz operation with main system clock) 8-bit resolution A/D converter: 4 channels I/O ports: 22 Serial interface: 1 channel • 3-wire serial I/O mode / UART mode: 1 channel • Timers: 6 channels • 16-bit timer: 1 channel • 8-bit timer/event counter: 2 channels • 8-bit timer: 1 channel • W atch timer: 1 channel • W atchdog timer: 1 channel • On-chip 16-bit multiplier • Power supply voltage: VDD = 4.5 to 5.5 V Document No. (1st edition)valid in only China Date Published Feb. 2003 NS CP(K) Printed in China  NEC Electronics 2003 µPD78F9189/9188CT APPLICATIONS Air-conditioner, White goods, etc ORDERING INFORMATION µPD78F9189CT/789188CT Part Number Package 32-pin plastic SDIP(400 mil) 32-pin plastic SDIP(400 mil) µPD78F9189CT µPD789188CT-xxx 2 Data Sheet (1st edition)valid in only China µPD78F9189/9188CT OVERVIEW OF FUNCTIONS Item Internal memory Flash memory High-speed RAM Minimum instruction execution time General-purpose registers Instruction set µPD78F9189CT 24 Kbytes 512 bytes µPD789188CT-xxx 16 Kbytes • 0.4/1.6 µs (@5.0-MHz operation with main system clock) 8 bits × 8 registers • 16-bit operations • Bit manipulations (set, reset, test) 8 bits × 8 bits = 16 bits Total: • CMOS I/O: • CMOS Input: • N-ch open drain: 26 17 4(Shared with A/D converter) 5 Multiplier I/O ports A/D converters Serial interfaces Timers 8-bit resolution × 4 channels 3-wire serial I/O/UART : 1 channel • • • • • 16-bit timer:1 channel 8-bit timer/event counter:2 channels 8-bit timer:1 channel Watch timer:1 channel Watchdog timer:1 channel Timer output Buzzer output Vectored interrupt sources Non-maskable Power supply voltage Operating ambient temperature Package Maskable 4 output 1 Internal: 10, External: 4 Internal: 1 VDD = 4.5 to 5.5 V TA = −40°C to +85°C 32-pin plastic SDIP (400 mil) Data Sheet (1st edition)valid in only China 3 µPD78F9189/9188CT 1.

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 V DD o r 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.
