• 26 Kbytes fast RAM and 6 Kbytes TPU microcode RAM

• 448 Kbytes Flash EEPROM with 5-V programming

• 5-V I/O system

• Serial system: queued serial multi-channel module (QSMCM), dual CAN 2.0B

controller

modules (TouCAN

)

• 50-channel timer system: dual time processor units (TPU3), modular I/O system

(MIOS1)

• 32 analog inputs: dual queued analog-to-digital converters (QADC64)

• Submicron HCMOS (CDR1) technology

• 272-pin plastic ball grid array (PBGA) packaging

• 40-MHz operation, -40

°C to 125 °C with dual supply (3.3 V, 5 V) (-55 °C to 125 °C

for the suffix A device)

• 32-bit architecture (PowerPC ISA architecture compliant)

• Core performance measured at 52.7-Kbyte Dhrystones (v2.1) @ 40 MHz

• Fully static, low power operation

• Integrated double-precision floating-point unit

• Precise exception model
