60MHz(16.67-ns cycle time)–
50MHz(20-ns cycle time)– 40MHz(25-ns cycle time)–
16×16and 32 × 32 MACoperations– 16×16dual MAC–
Harvard bus architecture– Atomic operations–
Fast interrupt response and processing–
Unified memory programming model– Code-efficient (in C/C++ and Assembly)

• Endianness: Little endian

• Lowcost for both device and system:– Single 3.3-V supply
– Nopower sequencing requirement– Integrated power-on and brown-out resets
– Small packaging, as low as 38-pin available– Lowpower
– Noanalog support pins

• Clocking:– Twointernal zero-pin oscillators
– On-chip crystal oscillator and external clock input– Watchdog timer module
– Missing clock detection circuitry

• Upto 22 individually programmable, multiplexed GPIO pins with input filtering

• Peripheral Interrupt Expansion (PIE) block that supports all peripheral interrupts

• Three 32-bit CPU timers

• Independent 16-bit timer in each Enhanced Pulse Width Modulator (ePWM)

On-chip memory– Flash, SARAM, OTP, Boot ROM available

• Code-security module

• 128-bit security key and lock– Protects secure memory blocks
– Prevents firmware reverse engineering
