• Description: 32-bit Arm -based General Purpose Microcontrollers Ml675k Seriesml675001/ml67q5002/ml67q5003 32-bit Arm -based General Purpose Microcontrollers
• Manufacturer: Oki Semiconductor

Pulse Width Modulation
The ML675001/Q5002/Q5003 contains two Pulse Width Modulation (PWM)
channels that can change the duty cycle of a waveform with a constant
period. The PWM output resolution is 16 bits for each channel.
A/D Converter
Successive approximation type A/D converter.
1. 10 bits x 4 channels
2. Sample and hold function
3. Scan mode and select mode are supported
4. Interrupt is generated after completion of conversion.
5. Conversion time: 5 µs (min).
Power Management
HALT, STANDBY and clock gear clock functions are supported as power save
functions.
1. HALT mode
2. STANDBY mode
3. Clock gear
4. Clock control by each function unit
The device has two clock systems, HCLK and CCLK. Configure HCLK
and CCLK frequency.
HCLK: CPU, bus control, synchronous serial interface, I
CCLK: Timers, PWM, SIO, AD converter, etc.
A/D converter, PWM, Timers, DRAMC, DMAC, UART(FIFO), SIO, Syn-
chronous SIO, I
HALT object
- CPU, internal RAM, AHB bus control
HALT mode setting: Set by the system control register.
Exit HALT mode due to: Reset, interrupt
Stops the clock for the entire device.
STANDBY mode setting: Specified by the system control register.
Exit STANDBY mode due to: Reset, external interrupt (other than EFIQ_N)

Built-In Flash ROM Programming
The robust features of the flash permit simple and optimized programming of
the flash-ROM.
1. There are three methods for programming the FLASH-ROM
2. Single power source for reading and programming of FLASH: 3.0V to
3. Programming units: 2 bytes
4. Selectable erasing size
5. Word program time: 20 µsec (2 bytes)
6. Sector/block erase time: 25 msec
7. Chip erase time: 100 msec
8. Write protection
9. Number of commands: 9
10. Highly reliable read/program
3.6V
- Programming via the JTAG interface.
- Programming using boot mode. Boot mode is used by the host to down-
- Programming via a user application running from external memory
- Sector erase: 2 Kbytes/sector
- Block erase: 64 Kbytes/block
- Chip erase: All memory cell
- Block protect: top address 8Kwords can be protected
- Chip protect: all words can be protected
- Sector programming: 1,000 times
- Data hold period: 10 years
load data to the FLASH ROM via the UART interface.
A program stored in the on-chip boot ROM is used to transfer the
incoming serial data on the UART interface to the internal Flash ROM.
Internal flash can be programmed by executing a user flash program-
ming application from external memory.
