C8051F351
50 MIPS, 8 kB Flash, 24-Bit ADC, 28-Pin Mixed-Signal MCU
Analog Peripherals
24-Bit ADC
- 0.0015% nonlinearity
- Programmable throughput up to 1 ksps
- 8 external inputs; programmable as single-ended or differential
- Programmable amplifier gain: 128, 64, 32, 16, 8, 4, 2, 1
- Data-dependent windowed interrupt generator
- Built-in temperature sensor (±3 °C)
Two 8-Bit Current DACs
Comparator
- 16 Programmable hysteresis values and response time
- Configurable to generate interrupts or reset
- Low current (0.4 µA)
Internal Voltage Reference
V_DD Monitor/Brown-out Detector
On-Chip Debug
- On-chip debug circuitry facilitates full speed, non-intrusive in-system
debug (no emulator required)
- Provides breakpoints, single stepping, watchpoints
- Inspect/modify memory, registers, and stack
- Superior performance to emulation systems using ICE-chips, target
pods, and sockets
Supply Voltage: 2.7 to 3.6 V
- Typical operating current: 17 mA at 50 MHz
16 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 50 MIPS throughput with 50 MHz clock
- Expanded interrupt handler
Memory
- 768 bytes data RAM
- 8 kB Flash; in-system programmable in 512 byte sectors (512 bytes are
reserved)
Digital Peripherals
- 17 port I/O; all 5 V tolerant
- Hardware SMBus™ (I2C™ compatible), SPI™, and UART serial ports
available concurrently
- 16-bit programmable counter array with three capture/compare modules,
WDT
- 4 general-purpose 16-bit counter/timers
- Realtime clock mode using PCA or timer and external clock source
Clock Sources
- Internal oscillator: 24.5 MHz, 2% accuracy supports UART operation
- External oscillator: Crystal, RC, C, or clock (1 or 2 pin modes)
- 2x clock multiplier to achieve 50 MHz internal clock
- Can switch between clock sources on-the-fly
Package
- 28-pin QFN (lead-free package)
