Accumulator handles 64-bit results (for a single
instruction) from 32- × 32-bit operations
Multiplication and division unit handles 32- × 32-bit
operations (multiplication instructions take one CPU
clock cycle)

Programmable at 1.62 V
For instructions and operands
■ On-chip data flash memory
8 Kbytes (Number of times of reprogramming: 100,000)
Erasing and programming impose no load on the CPU.
■ On-chip SRAM, no wait states

Clock frequency accuracy measurement circuit (CAC)
■ Real-time clock
Adjustment functions (30 seconds, leap year, and error)
Year and month display or 32-bit second display (binary
counter) is selectable
