On-chip Debug
-
On-chip debug circuitry facilitates full speed, non-
intrusive in-system debug (no emulator required)
- Provides breakpoints, single stepping,
inspect/modify memory and registers
- Superior performance to emulation systems using
ICE-chips, target pods, and sockets
Supply Voltage 2.7 to 3.6 V
-
Typical operating current: 6.6 mA @ 25 MHz;
14 µA @ 32 kHz
- Typical stop mode current: 0.1 µA
- Temperature range: –40 to +85 °C

High Speed 8051 µc Core
-
Pipelined instruction architecture; executes 70% of
instructions in 1 or 2 system clocks
- Up to 25 MIPS throughput with 25 MHz clock
- Expanded interrupt handler
Memory
-
256 bytes internal data RAM
- 8 kB Flash; 512 bytes are reserved in the 8 kB
devices
Digital Peripherals
-
8 Port I/O; All 5 V tolerant with high sink current
- Hardware enhanced UART and SMBus™ serial
ports
- Three general-purpose 16-bit counter/timers
- 16-bit programmable counter array (PCA) with three
capture/compare modules
- Real time clock mode using PCA or timer and
external clock source
Clock Sources
-
Internal oscillator: 24.5 MHz with ±2% accuracy
supports UART operation
- External oscillator: Crystal, RC, C, or clock (1 or 2
pin modes)
- Can switch between clock sources on-the-fly; Useful
in power saving modes
