C8051F54X_14 Datasheet, PDF (1/275 Pages) Silicon Laboratories – Mixed Signal ISP Flash MCU Family

Analog Peripherals
- 12-Bit ADC
• Up to 200 ksps
• Up to 25 external single-ended inputs
• VREF from on-chip VREF, external pin or V_DD
• Internal or external start of conversion source
• Built-in temperature sensor
- Two Comparators
• Programmable hysteresis and response time
• Configurable as interrupt or reset source
• Low current
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
- Low cost, complete development kit
Supply Voltage 1.8 to 5.25 V
- Typical operating current: 19 mA at 50 MHz;
Typical stop mode current: 1 µA
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
