TMP90C141
CMOS 8–Bit Microcontrollers
TMP90C141N/TMP90C141F
1. Outline and Characteristics
The TMP90C141 is a high-speed advanced 8-bit microcontroller
applicable to a variety of equipment.
With its 8-bit CPU, A/D converter, multi-function timer/
event counter and general-purpose serial interface integrated
into a single CMOS chip, the TMP90C041 allows the expansion
of external memories for programs (up to 64K byte) and data
(1M byte).
The TMP90C141N is a 64-pin shrink DIP product.
(SDIP64-P750)
The TMP90C041F is a 64-pin flat package product.
(QFP64-P1420A)
The characteristics of the TMP90C141 include:
(1) Powerful instructions: 163 basic instructions, including
Multiplication, division, 16-bit arithmetic operations, bit
manipulation instructions
(2) Minimum instruction executing time:
320ns (at 12.5MHz oscillation frequency)
(3) Internal RAM
(4) Memory expansion
External program memory: 63K byte
External data memory: 1M byte
(5) 8-bit A/D converter (6 channels)
(6) General-purpose serial interface (1 Channel)
Asynchronous mode, I/O interface mode
(7) Multi-function 16-bit timer/event counter (1 channel)
(8) 8-bit timers (4 channels)
(9) Stepping motor control port (2 channels)
(10) Input/Output ports (28 pins)
(11) Interrupt function:10 internal interrupts and 4 external
interrupts
(12) Micro Direct Memory Access (µDMA) function (11 channels)
(13) Watchdog timer
(14) Standby function (4 HALT modes)
