Compact MCU squeezes in more functions
The M16C/28 16bit microcontroller is billed as the first low-cost, low-pin-count device in Europe to offer a large peripheral set
The 64-pin (optional 80-pin) chip includes up to 96Kbyte Flash, 4Kbyte virtual EEPROM and 8Kbyte RAM and offers many peripheral features that have previously been unavailable in such a small (10 x 10mm), low-cost microcontroller. The device is ideally suited to many consumer and industrial applications such as white goods, motor control, HVAC, security systems and health goods.

The M16C/28 offers many features that are unusual for a device in its class.
These include: up to five serial interfaces that offer support for synchronous, asynchronous, multimaster I2C and subsets of serial peripheral interface and smart card mode ISO7816; a fast (3.3us) 10bit ADC with up to 24 channels; a large number of conversion modes and two sample and hold circuits for simultaneous sampling of two signals (as required in electrical motor control systems); many powerful timers with special three-phase PWM electrical motor modes, including an eight channel 16bit timer, an additional 16bit free running timer with eight input capture/output compare channels, and a watchdog timer; and a two channel DMA controller.
The M16C/28 is based on the high performance M16C CPU which features very high code density, a double-banked register set for fast interrupt response and a multiplier to further enhance performance.
The device offers 3 to 5V operation at 20MHz clock, and 2.7 to 5V operation at 10MHz.
It has very low power consumption, for example just 16mA typical at 5V/20MHz and 25uA at 3V/32kHz, and excellent electromagnetic behaviour.

Other features of the M16C/28 include comprehensive clock generation functions, such as main clock, subclock and an internal ring oscillator for start-up and emergency shutdown operation, a low voltage detect circuit, seven-priority-level interrupt controller with 25 internal, eight external and four software sources, and up to 71 I/O lines.
The device also offers additional features that facilitate the one-shunt motor drive algorithm.
This cuts costs in white goods motor control by eliminating a few parts such as an expensive current sensor in the phases of the motor.
The M16C/28 is available immediately in 64- and 80-pin QFP packages as small as 10 x 10mm (64-pin).
It is supported by the popular PC7501 in-circuit, real-time emulator.
An evaluation board is currently under development.
A new version of the device with CAN, the M16C/29, is under development and will be targeting automotive body applications later this year.
Another version with wide temperature options up to 125C is also under development.
