GENERAL DESCRIPTION
This version: May 2001 Previous version: Feb. 2001
NOTICE: MSM66P573/MSM66Q573Y/MSM66Q573LY are supplied as stock lasts.
The MSM66573 family of highly functional CMOS 16-bit single chip microcontrollers utilize the nX-8/500S, Oki's proprietary CPU core. A wide variety of internal multi-functioned timers provide timer functions such as compare out, capture input, event counter, auto reload, and PWM, and can be used for periodic and timed measurements. And 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 MSM66573 family of microprocessors is optimally suited for the system control of small-sized low power devices. A three channel serial interface and a high-speed bus interface that has separate address and data buses and does not require external address latches are provided as interfaces to external devices. With a 16-bit CPU core that enables high-speed 16-bit arithmetic computations and a variety of bit processing functions, this general-purpose microcontroller is optimally suited for Digital Audio devices such as a Mini-Disc and an MP3 player. The flash ROM version (MSM66Q573L) programmable with a single 3 V power supply (2.4 to 3.6 V) and flash ROM version (MSM66Q573) programmable with a single 5 V power supply (4.5 to 5.5 V) 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. MSM66Q573L and MSM66Q573 with flash memory programmable with single power supply In addition to the regular mask ROM version, the family includes these versions with 64KB of flash memory that can be programmed using a single power supply. For the MSM66Q573L, an internal booster circuit derives the necessary program voltage from the device's low (2.4 to 3.6 V) power supply, and the program voltage for the MSM66Q573 is provided with a single 5 V power supply (4.5 to 5.5 V). 4. Multifunction, high-precision A/D converter The family includes a high-precision 10-bit analog-to-digital converter with eight channels and is ideal for such analog control functions as processing audio signals, processing sensor inputs, detecting key switch states, and controlling battery use in portable equipment. Each channel has its own result register readily accessible from the software. In addition to single-channel conversions, there is also a scan function offering automatic conversion from the user's choice of starting channel through to the last channel. 5. Multifunction PWM The family supports both 8- and 16-bit PWM operation. Choosing between the time-base counter output or overflow from an 8-bit auto-reload timer as the PWM counter clock source provides a wide number of possibilities over a broad frequency range. The 16-bit PWM configuration supports a high-speed synchronization mode that generates a high-precision output signal with less ripple suitable for digital-to-analog control applications. 6. Programmable pull-up resistors Building the pull-up resistors into the chip contributes to overall design compactness. Making them programmable on a per-bit basis allows complete flexibility in circuit board layout and system design. These programmable pull-up resistors are available for all I/O pins not already assigned specific functions (such as the oscillator connection pins). 7. High-speed bus interface The interface to external devices uses separate data and address buses. This arrangement permits rapid bus access for controlling the system from the microcontroller. 8. Wide support for external interrupts There are a total of seven interrupt channels for use in communicating with external devices: six for maskable interrupts and one for non-maskable interrupts.
