C8051F330/1/2/3/4/5
Mixed-Signal ISP Flash MCU
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
- 768 bytes internal data RAM (256 + 512)
- 8 kB ('F330/1), 4 kB ('F332/3), or 2 kB ('F334/5)
Flash; In-system programmable in 512-byte Sec-
tors—512 bytes are reserved in the 8 kB devices
Digital Peripherals
- 17 Port I/O; All 5 V tolerant with high sink current
- Hardware enhanced UART, SMBus™, and
enhanced SPI™ serial ports
- Four 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 exter-
nal clock source
Clock Sources
- Two internal oscillators:
•
24.5 MHz with ±2% accuracy supports crystal-less
UART operation
•
80/40/20/10 kHz low frequency, low power
-
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
