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
- 4352 bytes internal data RAM (256 + 4096)
- 64 kB (‘F93x) or 32 kB (‘F92x) Flash; In-system pro-
grammable in 1024-byte sectors—1024 bytes are
reserved in the 64 kB devices
Digital Peripherals
- 24 or 16 port I/O; All 5 V tolerant with high sink 
current and programmable drive strength-Hardware
SMBus™ (I²C™ Compatible), 2 x SPI™, and UART
serial ports available concurrently
- Four general purpose 16-bit counter/timers
- Programmable 16-bit counter/timer array with six
capture/compare modules and watchdog timer
- Hardware SmaRTClock operates down to 0.9 V and
requires less than 0.5 µA supply current
Clock Sources
- Internal oscillators: 24.5 MHz, 2% accuracy
supports UART operation; 20 MHz low power
oscillator requires very little bias current
- External oscillator: Crystal, RC, C, or CMOS Clock
- SmaRTClock oscillator: 32 kHz Crystal or internal
self-oscillate mode
- Can switch between clock sources on-the-fly; useful
in implementing various power saving modes
Packages
- 32-pin QFN (5 x 5 mm)
- 24-pin QFN (4 x 4 mm)
- 32-pin LQFP (7 x 7 mm, easy to hand-solder)
