TMP90C801

TOSHIBA TLCS-90 Series TMP90C800/801 CMOS 8–Bit Microcontrollers TMP90C800N/TMP90C801N TMP90C800F/TMP90C801F 1. Outline and Characteristics The TMP90C800 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 TMP90C800 allows the expansion of external memories for programs and data (up to 56K bytes). The function of TMP90C800 is exactly same as the TMP90C400 except the internal ROM/RAM size. The TMP90C801 is the same as the TMP90C800 but without the ROM. The TMP90C800N/801N is in a shrink Dual Inline Package (SDIP64-P-750). The TMP90C800F/801F is in a Quad Flat package (QFP64-P-1420A) The characteristics of the TMP90C800 include: (1) Powerful instructions: 163 basic instructions, including Multiplication, division, 16-bit arithmetic operations, bit manipulation instructions Minimum instruction executing time: 320ns (at 12.5MHz oscillation frequency) (3) (2) w w .D w t a S a e h Internal ROM: 8K bytes (The TMP90C801 does not have a built-in ROM) (4) Internal RAM: 256 bytes (5) Memory expansion External memory: 56K bytes (6) General-purpose serial interface (1 channel) Asynchronous mode, I/O interface mode (7) 8-bit timers (4 channel): (2 external clock input) (8) Port with zero-cross detection circuit (4 input) (9) Input/Output ports (56 pins) - Ports with programmable pull-up resistor (22 pins) - Allows I/O sele...
