M16C

M16C is the name of a family of 16-bit - microcontrollers . The first versions were developed by Mitsubishi Electric and are now being developed and manufactured by Renesas Electronics , the outsourced semiconductor division of Mitsubishi.

The M16C family consists of the M16C / Tiny, M16C / 10, M16C / 20, M16C / 30, M16C / 50, M16C / 60 and M16C / 80 series with different versions.

For example, the clock frequency varies from 10 to 32 MHz and the internal memory from 0 to 768 KByte.

They all have in common:

• the register architecture :
  • double, switchable working register set 4 * 16 bit (can also be used as 8 or 32 bit register)
  • Address and segment registers
  • separate stack pointers for interrupts and subroutines
• the instruction set (16 bit)
• the address range: 1 Mbyte
• the standard peripherals (except M16C / Tiny and M16C / 10):
  • 11 * 16 bit timer / counter
  • UART / Clock Synchronous Serial Interface
  • 10 bit A / D converter
  • DMA controller
  • CRC Calculator
  • Watchdog timer

Typical applications for the M16C are industrial controls and automotive subsystems.
