April 2004, Rev 2.0
Pulse Width Modulation
This MCU contains two channels of Pulse Width Modulation (PWM) function
which 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 s (min).
Power Management
HALT, STANDBY and clock gear clock control functions are supported as
power save functions.
1. HALT mode
HALT object
- CPU, internal RAM, AHB bus control
HALT mode setting: Set by the system control register.
Exit HALT mode due to: Reset, interrupt
2. STANDBY mode
Stops the clock for the entire device.
STANDBY mode setting: Specied by the system control register.
Exit STANDBY mode due to: Reset, external interrupt (other than EFIQ_N)
3. Clock gear
The MCU has two clock systems, HCLK and CCLK. Configure HCLK
and CCLK frequency.
HCLK: CPU, bus control, synchronous serial interface, I2C.
CCLK: Timers, PWM SIO, AD converter, etc.
4. Clock control by each function unit
AD converter, PWM, Timers, DRAMC, DMAC, UART(FIFO), SIO, SSIO,
I2C.
Built-In Flash ROM Programming
The robust features of the ash permit simple and optimized programming of
the ash-ROM.
1. There are three methods for programming the FLASH-ROM
- Programming via the JTAG interface
- Programming using boot mode
Boot mode is used by the host to download 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.
- Programming via a user application running from external memory
Internal ash can be programmed by executing a user ash program-
ming application from external memory.
2. Single power source for reading and programming of FLASH: 3.0V to
3.6V
3. Programming units: 2 bytes
4. Selectable erasing size
- Sector erase: 2 KBytes/sector
- Block erase: 64 KBytes/block
- Chip erase: All memory cell
5. Word program time: 20 sec (2 bytes)
6. Sector/block erase time: 25 msec
7. Chip erase time: 100 msec
8. Write protection
- Block protect: top address 8Kwords can be protected
- Chip protect: all words can be protected
9. Number of commands: 9
10. Highly reliable read/program
- Sector programming: 1,000 times
- Data hold period: 10 years
