TMP90C803A

TOSHIBA TLCS-90 Series TMP90C802A/803A CMOS 8–Bit Microcontrollers TMP90C802AP/TMP90C802AM TMP90C803AP/TMP90C803AM 1. Outline and Characteristics The TMP90C802A is a high-speed advanced 8-bit microcontroller applicable to a variety of equipment. With its 8-bit CPU, ROM, RAM, timer/event counter and general-purpose serial interface integrated into a single CMOS chip, the TMP90C802A allows the expansion of external memories (up to 56K byte). The TMP90C803A is the same as the TMP90C802A but without the ROM The TMP90C802AP/803AP is in a DIP product. The TMP90C802AM/8803AM is in a SOP (Small Outline Package). The characteristics of the TMP90C802A include: (1) Powerful instructions: 163 basic instructions, including Multiplication, division, 16-bit arithmetic operations, bit manipulation instructions (2) (3) (4) (5) (6) (7) (8) (9) (10) (11) (12) (13) Minimum instruction executing time: 320ns (at 12.5MHz oscillation frequency) Internal ROM: 8K byte (The TMP90C803A does not have a built-in ROM.) Internal RAM: 256 byte Memory expansion External memory: 56K byte General-purpose serial interface (1 channel) Asynchronous mode, I/O interface mode 8-bit timers (4 channels): (1 external clock input) Port with zero cross detection circuit (1 input) Input/Output ports (TMP90C802A: 32 pins, 90C803A: 6 pins) Interrupt function: 8 internal interrupts and 3 external interrupts Micro Direct Memory Access (DMA) function (4 channels) Watchdog timer Standby function (4 HALT modes) w w .D w t ...
