Renesas releases trimmed versions of the M16C/60

These are trimmed versions of the M16C/60 group and are compatible with previous products.

The M16C/63 range can operate between 1.8 and 5.5V.

It uses the M16C/60 16-bit CISC CPU core.

At 1.8 to 2.7 V the CPU runs at speeds up to five MHz.

It can achieve 20MHz operation from 2.7 to 5.5V.

The devices have low power consumption.

In full active mode, with Vcc=3V, WDT, RTC and external 32kHz crystal running and the CPU clocked at 20MHz, a total power consumption of 9mA is possible.

In the devices' wait mode, with WDT, RTC and external 32kHz crystal running, 3.5uA is achievable at Vcc=1.8V.

New features include a CEC (consumer electronics control) circuit, low-voltage detection (LVD) circuit, real-time clock with full calendar functionality (RTC), high-precision (40MHz) on-chip oscillator and watchdog timer with an independent oscillator (125kHz).

A hardware multi-master I2C-bus has replaced the simplified I2C-bus.

The on-chip peripheral functions have been improved to include a fast A/D converter, 6 USART, 2 SIO, CRC unit and four DMA controllers.

The 10-bit A/D converter achieves a fast conversion speed and offers 26 channels.

The devices are available with on-chip Flash and Ram memory in density combinations of 128kB/12kB and 256kB/20kB.

The ICs also have an extra flash memory for data storage.

Two banks of 4kB DataFlash*2 are included, each with an endurance of 10,000 cycles in both read and write operations, along with a bank of 16kB to store a customised boot-loader.

The M16C/63 will be available in 80-pin and 100-pin QFP packages.

The M16C/63 is suited for portable applications such as glucose meters and low-power metering applications.

The integrated CEC circuit makes the M16C/63 ideal for a general power management unit in the HDMI environment for home entertainment equipment.

The new E8a on-chip debugging emulator is available as a development environment.

The E8a can also be used as a flash programmer.
