C8051F310/1/2/3/4/5/6/7
8/16 kB ISP Flash MCU Family
Analog Peripherals
- 10-Bit ADC (C8051F310/1/2/3/6 only)
• Up to 200 ksps
• Up to 21, 17, or 13 external single-ended or differen-
tial inputs
• VREF from external pin or VDD
• Built-in temperature sensor
• External conversion start input
- Comparators
• Programmable hysteresis and response time
• Configurable as interrupt or reset source
(Comparator0)
• Low current (< 0.5 µA)
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
- Complete development kit
Supply Voltage 2.7 to 3.6 V
- Typical operating current: 5 mA at 25 MHz;
11 µA at 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
- 1280 bytes internal data RAM (1024 + 256)
- 16 kB (C8051F310/1/6/7) or 8 kB (C8051F312/3/4/5)
Flash; In-system programmable in 512-byte sectors
Digital Peripherals
- 29/25/21 Port I/O;
All 5 V tolerant with high sink current
- Hardware enhanced UART, SMBus™, and SPI™
serial ports
- Four general purpose 16-bit counter/timers
- 16-bit programmable counter array (PCA) with five
capture/compare modules
- Real time clock capability using PCA or timer and
external clock source
Clock Sources
- Internal oscillator: 24.5 MHz with ±2% accuracy
supports crystal-less 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
Packages
- 32-pin LQFP (C8051F310/2/4)
- 28-pin QFN (C8051F311/3/5)
- 24-pin QFN (C8051F316/7)
