TMP90C846

TOSHIBA TLCS-90 Series CMOS 8–Bit Microcontroller TMP90C846F 1. Outline and Characteristics The TMP90C846 is an advanced 8-bit microcontroller developed for application in the control of HDD/FDD highspeed mechanisms. The built-in functions include a high-speed A/D converter (minimum sampling rate: 400ns @ 10MHz) with an external start function, and a D/A converter. The TMP90C846, integrates 8-bit CPU, ROM, RAM, high-speed A/D converter, D/A converter, and multi-function timer/event counter in a single-chip. The TMP90C846 uses a 44-pin mini flat package (QFP44-P1414D). The following are the features of the TMP90C846: (1) Highly efficient instruction set: 163 basic instructions Division and multiplication instructions, 16-bit operation instruction and bit manipulation operation instructions and bit operation instructions. Minimum instruction executing time: 400ns (@ 10MHz) Built-in ROM: 8K bytes (4) (5) Built-in RAM: 256 bytes Memory expansion capability External program memory: 56K bytes External data memory: 56K bytes Highly-speed A/D converter (2 channels) Minimum sampling rate: 400ns (@ 10MHz) 16-byte FIFO RAM (conversion data storage) External start, software start (one-time conversion, repeat conversion 8-bit voltage output type D/A converter (2 channels) Multi-function 16-bit timer/event counter (1 channel) 8-bit timer (4 channels) Interrupt function: 9 internal, 4 external Micro DMA function (10 channels) Watchdog timer function Zero cross detector (2 pins) I/O port...
