C8051F320
C8051F320/1
Full Speed USB, 16 k ISP FLASH MCU Family
Analog Peripherals
- 10-Bit ADC
Up to 200 ksps
Up to 17 or 13 external single-ended or differential
inputs
VREF from external pin, internal reference, or VDD
Built-in temperature sensor
External conversion start input
- Two Comparators
- Internal Voltage Reference
- POR/Brown-Out Detector
USB Function Controller
- USB specification 2.0 compliant
- Full speed (12 Mbps) or low speed (1.5 Mbps)
operation
- Integrated clock recovery; no external crystal
required for full speed or low speed
- Supports eight flexible endpoints
- 1 kB USB buffer memory
- Integrated transceiver; no external resistors required
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
Voltage Regulator Input: 4.0 to 5.25 V
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
- 2304 bytes internal RAM (1k + 256 + 1k USB FIFO)
- 16 kB Flash; In-system programmable in 512-byte
sectors
Digital Peripherals
- 25/21 Port I/O; All 5 V tolerant with high sink current
- Hardware enhanced SPI™, enhanced UART, and
SMBus™ serial ports
- Four general purpose 16-bit counter/timers
- 16-bit programmable counter array (PCA) with five
capture/compare modules
- Real time clock mode using external clock source
and PCA or timer
Clock Sources
- Internal Oscillator: 0.25% accuracy with clock
recovery enabled. Supports all USB and UART
modes
- External oscillator: Crystal, RC, C, or Clock
(1 or 2 pin modes)
- Can switch between clock sources on-the-fly;
useful in power saving strategies
RoHS Compliant Packages
- 32-pin LQFP (C8051F320)
- 28-pin QFN (C8051F321)
Temperature Range: –40 to +85 °C
