ML670100
OKI’s High-Performance CMOS 32-Bit Single Chip Microcontroller
GENERAL DESCRIPTION
The ML670100 is a high-performance 32-bit microcontroller combining a RISC based, 32-bit CPU core -
the ARM7TDMI
TM - with memory and such peripheral circuits as timers, serial ports, and analog-to-
digital converter. This combination of 32-bit data processing, built-in memory, and on-chip peripherals
make it ideal for controlling equipment requiring both high speed and high functionality. An external
memory controller supports direct connection to memory and peripheral devices for adding even more
functionality.
FEATURES
Operating Voltage
2.7 to 3.6V
Operating Frequency 25MHz maximum(3.0 to 3.6V)
On-chip memory
-ROM: 128 kilobytes
-RAM: 4 kilobytes
I/O Function
I/O ports: 8 bits x 9, I/O directions are specified at the bit level
Timer
-Flexible timer (16-bit multi-function timer with six channels)
Choice of operating modes: auto-reload timer, compare output, PWM
and capture
-Time base counter with WDT function
Serial Port
-One asynchronous serial port (UART) with baud rate generator
-Two clock synchronous serial port
A-to-D Converter
-8-bit resolution A-to-D converter with eight analog input ports
Interrupt
Controller
-Support for 28 interrupt sources: 9 external and 19 internal
-Choice of eight priority levels for each source
External Memory
Controller
-Direct connection to ROM, SRAM, DRAM and peripheral devices
-Support for four banks: two for ROM, SRAM and I/O devices plus two for
DRAM
-User-configurable bus width (8/16 bits) and wait control and other
parameters for accessing memory and external devices
Clock Generator
-Built-in crystal oscillation circuit and PLL
-Choice of divider ratio (1/1, 1/2, 1/4) for adjusting operating clock frequency
to match the load of processing
