10-bit A/D converter (successive approximation conversion type)
• 10-bit resolution, 4 channels
• Successive approximation type: Conversion time of 5.6 µs at 25 MHz
• Internal sample and hold circuit
• Conversion mode: Single conversion/scanning conversion/repeated conversion/stop conversion selective
• Start: Software/external trigger/internal timer selective
16-bit reload timer
• 3 channels
• Internal clock: 2 clock cycle resolution, divide by 2/8/32 selective
Other interval timers
• 16-bit timer: 3 channels (U-TIMER)
• PWM timer: 4 channels
• Watchdog timer: 1 channel
Bit search module
First bit transition “1” or “0” from MSB can be detected in 1 cycle.
Interrupt controller
• External interrupt input: Non-maskable interrupt (NMI), normal interrupt × 4 (INT0 to INT3)
• Internal interrupt incident:UART, DMA controller (DMAC), A/D converter, U-TIMER and delayed interrupt
module
• Priority levels of interrupts are programmable except for non-maskable interrupt (in 16 steps).
Others
• Reset cause: Power-on reset/hardware standby/watchdog timer/software reset/external reset
• Low-power consumption mode: Sleep mode/stop mode
• Clock control
Gear function: Operating clocks for CPU and peripherals are independently selective.
Gear clock can be selected from 1/1, 1/2, 1/4 and 1/8 (or 1/2, 1/4, 1/8 and 1/16).
However, operating frequency for peripherals is less than 25 MHz.
• Packages: LQFP-100 and QFP-100
• CMOS technology (0.35 µm)
• Power supply voltage
5 V: CPU power supply 5.0 V ±10% (internal regulator)
A/D power supply 2.7 V to 3.6 V
3 V: CPU power supply 2.7 V to 3.6 V (without internal regulator)
A/D power supply 2.7 V to 3.6 V
