Instructions in 1 or 2 system clocks
\- 48 MIPS and 25 MIPS versions available.
\- Expanded interrupt handler
Memory
\- 4352 or 2304 Bytes RAM
\- 64 or 32 kB Flash; In-system programmable in 512-byt
sectors
Digital Peripherals
\- 40/25 Port I/O; All 5 V tolerant with high sink current
\- Hardware enhanced SPI™, SMBus™, and one or two
enhanced UART serial ports
\- Four general purpose 16-bit counter/timers
\- 16-bit programmable counter array (PCA) with five cap
ture/compare modules
\- External Memory Interface (EMIF)
Clock Sources
\- Internal Oscillator: ±0.25% accuracy with clock recover
enabled. Supports all USB and UART modes
\- External Oscillator: Crystal, RC, C, or clock (1 or 2 Pin
modes)
