Description
M16C/26 Group
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
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
