MARC4 – 4-bit Universal Microcontroller
The M44C510E is a member of the TEMIC Semiconductors family of 4-bit single-chip microcontrollers. It contains
ROM, RAM, up to 34 digital I/O pins, up to 10 maskable external interrupt sources, 4 maskable internal interrupts,
a watchdog timer, interval timer, 2 x 8-bit multifunction timer/counter module and a versatile software configurable
on-chip system clock module.
Features / Benefits
D Programmable system clock with prescaler and five
different clock sources:
– 4-MHz crystal oscillator
– 32-kHz crystal oscillator
– RC-oscillator fully integrated
– RC-oscillator with external resistor adjustment
– External clock input
D Wide supply voltage range (2.2 V to 6.2 V)
D Very low halt current (< 1 mA)
D 4 KByte ROM, 256 x 4-bit RAM
D 8 hard– and software interrupt priority levels
D Up to 10 external and 4 internal interrupts, bitwise
maskable with programmable priority level
D Up to 34 I/O lines including 8 high drive I/O-lines
(20 mA, VDD = 5 V)
D I/O ports – bitwise configurable with combined inter-
rupt handling (for serial I/O applications)
D 2 x 8-bit multifunction timer/counters
D Coded reset and watchdog timer **
D Power-on reset and “brown out” function
D Various power-down modes
D Efficient, hardware-controlled interrupt handling
D High-level programming language in qFORTH
D Comprehensive library of useful routines
D Windows 95/ NT based development tools
(** mask option)
