(Conversion time of 20µs/16MHz)
— Serial interface Incorporated buffer RAM (Auto transfer for 1 to 32bytes),
1channel
Incorporated 8-bit, 8-stage FIFO
(Auto transfer for 1 to 8bytes), 1channel
— Timer 8-bit timer
8-bit timer/counter
19-bit time base timer
— PWM output 12bits, 2channels
(repetitive frequency 62.5kHz/16MHz)
• Interruption 10 factors, 10 vectors, multi-interruption possible
• Standby mode SLEEP/STOP
• Package 64-pin ceramic PQFP
Note) Mask option depends on the type of the CXP81100. Refer to the Products List for details.
