DMAC
DMAC in descriptor format for placing transfer parameters on to the main memory.
Capable of transferring a maximum of eight internal and external factors combined.
Three channels for external factors
Bit Search Module
Searches in one cycle for the position of the bit that changes from the MSB in one word to the initial 1/0.
Timers
•16-bit OCU ´ 8 channels, ICU ´ 4 channels, Free-run timer ´ 1 channel
• 8/16-bit up/down timer/counter (8-bit ´ 2 channels or 16-bit ´ 1 channel)
• 16-bit PPG timer ´ 6 channels. The output pulse cycle and duty can be varied as desired.
• 16-bit reload timer ´ 4 channels
D/A Converter
• 8-bit ´ 3 channels
A/D Converter (Sequential Comparison Type)
• 10-bit ´ 8 channels
• Sequential conversion method (conversion time : 5.0 ms@33 MHz)
• Single conversion or scan conversion can be selected, and one-shot or continuous or stop conversion mode
can be set respectively.
• Conversion starting function by hardware/software.
Serial I/O
• UART´ 4 channels. Any of them is capable of serial transfer in sync with clock attached with the LSB/MSB
switching function.
• Serial data output and serial clock output are selectable by push-pull/open drain software.
• A 16-bit timer (U-timer) is contained as a dedicated baud rate generator allowing any baud rate to be generated.
Clock Switching Function
• Gear function : Operating clock ratios to the basic clock can be set independently for the CPU and peripherals
from four types, 1 : 1, 1 : 2, 1 : 4 or 1 : 8.
Interrupt Controller
External interrupt input (16 channels in total)
• Allows the rising edge/falling edge/H level/L level to be set.
Internal interrupt factors
• Interrupt by resources and delay interrupt
Others
• Reset cause : Power on reset/watchdog timer/software reset/external reset
• Low power consumption mode : Sleep/stop
• Package : 144-pin LQFP
• CMOS technology (0.35 mm)
• Power supply voltage : 3.15 V to 3.6 V
