MB89170/A Series
DTMF generator
DESCRIPTION
The MB89170/170A series has been developed as a general-purpose version of the F²MC-8L(F²MC stands for FUJITSU Flexible Microcontroller)
family consisting of proprietary 8-bit, single-chip microcontrollers. In addition to a compact instruction set, the microcontrollers
contain a great variety of peripheral functions such as timers, a serial interface, a DTMF generator, and external interrupts,
making it suitable for circuit control such as required in telephones.
FEATURES
- F²MC-8L family CPU core
- Maximum memory space: 64 Kbytes
- Minimum execution time/interrupt processing time

- MB89170 series: 1.1µs/10µs (at 3.58 MHz oscillation)
- MB89170A series: 0.6µs/5.4µs (at 7.16 MHz oscillation)
- Dual-clock control system
- I/O ports: max. 37 ports
- 21-bit timebase counter
- Watch prescaler, (MB89170/170A series only)
- Watchdog timer
- 8/16-bit timer/counter: 1 channel
- 8-bit serial I/O: 1 channel
- DTMF generator(MB89170/170A series only)
- Selectable oscillation frequency(MB89170A series only)
- External interrupt 1: Three channels are independent and capable of using for wake-up from low-power consumption modes (with an edge detection function).
- External interrupt 2 (wake-up): Eight channels are independent and capable of using for wake-up from low-power consumption modes (with an "L" level detection function).
- Low-power consumption modes(stop mode, sleep mode, watch mode, and subclock mode)
- CMOS technology
