Internal Voltage Reference
V_DD Monitor/Brown-out Detector
On-Chip JTAG Debug & Boundary Scan
- On-chip debug circuitry facilitates full speed, non-intrusive in-system
debug (no emulator required)
- Provides breakpoints, single stepping, watchpoints, stack monitor
- Inspect/modify memory and registers
- Superior performance to emulation systems using ICE-chips, target
pods, and sockets
- IEEE1149.1 compliant boundary scan
High-Speed 8051 µC Core
- Pipelined instruction architecture; executes 70% of instructions in 1 or 2
system clocks
- Up to 100 MIPS throughput with 100 MHz system clock
- 16 x 16 multiply/accumulate engine (2-cycle)
Memory
- 8448 bytes data RAM
- 128 kB Flash; in-system programmable in 1024-byte sectors (1024 bytes
are reserved)
- External parallel data memory interface
Digital Peripherals
- 32 port I/O; all are 5 V tolerant
- Hardware SMBus™ (I2C™ Compatible), SPI™, and two UART serial
ports available concurrently
- Programmable 16-bit counter/timer array with six capture/compare
modules
- 5 general-purpose 16-bit counter/timers
- Dedicated watchdog timer; bidirectional reset
- Real-time clock mode using Timer 3 or PCA
Clock Sources
- Internal oscillator: 24.5 MHz, 2% accuracy supports UART operation
