Description

The M16C/26 group of single-chip microcomputers incorporates Renesas' 16-bit M16C/60 Series CPU core,

fabricated in a high-performance silicon gate CMOS process and packaged in 48-pin plastic molded LQFPs.

Noted for fast instruction processing, these microcomputers are designed to operate using a sophisticated,

yet highly-efficient instruction set. Their design is optimized for general application to the home, office, audio,

and industrial sectors.

The M16C/26 group comprises a range of products of varied configuration. Note that the term "Virtual

EEPROM" is used in this manual to denote Flash ROM blocks capable of a very high number of erase/write

cycles. Simulated byte or word erase/write (E/W) requires firmware (available from Renesas).

Features

Memory ..................................................................Flash ROM 24K to 64K bytes (1K minimum erase/write cycles)

plus Flash ROM 2K bytes x 2 blocks as Virtual EEPROM

(10K minimum erase/write cycles, 100K typical erase/write cycles)

Erase/write voltage for flash is from Vcc = 2.7 to 5.5 V

RAM 1K to 2K bytes.

Shortest Instruction Execution Time ......................50ns (f(XIN)=20 MHz, Vcc=3.0V to 5.5V)

100ns (f(Xin)=10 MHz, Vcc=2.7V to 5.5V)

Supply Voltage ......................................................Vcc = 3.0V to 5.5V (f(Xin) = 20MHz, no wait)

Vcc = 2.7V to 5.5V (f(Xin) = 10MHz, no wait)

Low Power Consumption .......................................0.7uA (typ) Icc, Stop mode, Vcc = 3.0V,

1.8 uA (typ) Icc at 32kHz Wait mode, Vcc = 3.0V

25uA (typ) Icc at 32KHz mode with RAM access (Flash sleep)

16mA (typ) Icc at 20 MHz, Vcc = 5.0V

Interrupts ...............................................................20 internal and 7 external interrupt sources

4 software interrupt sources; 7 priority levels

Serial I/O ...............................................................2 U(S)ART/SIO (UART 0/1)

1 U(S)ART/SIO/I2C bus/IEBus (UART 2) (Note 1,2)

DMAC ....................................................................2 Channels

A-D Converter .......................................................10 bits X 8 channels

Watchdog Timer ....................................................1 15-bit timer (switchable to internal ring oscillator)

Timers ...................................................................8 16-bit timers

5 Timer A (Event counter, Event timer, One-shot generator, Pulse

width measurement generation, Quadrature counter)

3 Timer B (Event counter, Period measurement,

Pulse width measurement, Timer)

3-phase PWM generators for motor control

Key-on Wake Up ...................................................4 inputs

Programmable I/O .................................................38 lines

Brown-out Monitor .................................................With interrupt, reset and RAM retention flag capability.

Clock Generation Circuit .......................................3 built-in clock generation circuits

2 internal clock generators (supports ceramic or quartz oscillator);

crystal failure detect

1 internal ring oscillator
