S 1 emiconductor MSM66577 Family
16-Bit Microcontroller
This version: Feb. 2001 Previous version: Oct. 2000
GENERAL DESCRIPTION
The MSM66577 family of highly functional CMOS 16-bit single chip microcontrollers utilizes the nX-8/500S, Oki's proprietary CPU core. Four channels of serial ports, consisting of two channels of synchronous serial ports with 32-byte FIFO registers and two channels of UART/synchronous serial ports, enable easy interfacing with external peripheral LSI devices such as an encoder/decoder or servocontroller. A switching function permits selection of separate address and data lines or multiplexed lines for the external bus interface to correspond to various peripheral LSI devices. With features such as a clock gear function, dual clock function, STOP/HALT mode, programmable pull-up ports in which individual bits can be programmed, and a small, thin package, the MSM66577 family of microprocessors is optimally suited for the system control of small-sized low power devices. The flash ROM version (MSM66Q577LY) programmable with a single 3V power supply (3.0 to 3.6V) and flash ROM version (MSM66Q577) programmable with a single 5V power supply (4.5 to 5.5V) are also included in the family.

SPECIAL FEATURES
1. High-performance CPU The family includes the high-performance CPU, powerful bit manipulation instruction set, full symmetrical addressing mode, and ROM WINDOW function, and also provides the best optimized C compiler support. 2. A variety of power saving modes Attaching a 32.768-kHz crystal produces a real-time clock signal from the internal clock timer. Use of a single clock in place of dual clocks is possible. The clock gear function allows a 1/2 × or 1/4 × main clock to be selected for the CPU operating clock. Switching the CPU clock to 32.768-kHz signal, 1/2 × main clock, or 1/4 × main clock, then produces operation in a low power consumption mode. The family provides a wide range of standby control functions. In addition to the usual STOP mode that stops the oscillator, there are the quick restart STOP mode that shuts down the CPU and peripherals but leaves the oscillator running, and the HALT mode that shuts down the CPU but leaves the peripherals running. 3. Variety of multifunctional serial ports The family includes two channels of built-in synchronous serial ports with 32-byte FIFO implementing an auto transfer function. The family allows multi-byte 1-frame information which consists of address, command, and data to be easily and efficiently transmitted to or received from a serial interface type peripheral LSI device. The family also allows multi-byte character information to be easily and efficiently transmitted to or received from an LCD module. In addition, the family has two channels of combined UART/synchronous serial ports, and provides four channels of serial interfaces.

4. MSM66Q577LY and MSM66Q577 with flash memory programmable with single power supply In addition to the regular mask ROM version, the family includes these versions with 128KB of flash memory that can be programmed using a single power supply. For the MSM66Q577LY, an internal booster circuit derives the necessary program voltage from the device's low (3.0 to 3.6V) power supply, and the program voltage for the MSM66Q577 is provided with a single 5 V power supply (4.5 to 5.5 V). 5. High-precision A/D and D/A converters The family includes a high-precision 10-bit analog-to-digital converter with eight channels and 8-bit digital-toanalog converter with two channels.
