Analog Peripherals
- 12-Bit ADC
• Up to 200 ksps
• Up to 25 external single-ended inputs
• VREF from on-chip VREF, external pin or VDD
• 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
C8051F54x
Mixed Signal ISP Flash MCU Family
Memory
- 1280 bytes internal data RAM (256 + 1024 XRAM)
- 16 or 8 kB Flash; In-system programmable in
512-byte Sectors
Digital Peripherals
- 25 or 18 Port I/O; All 5 V tolerant
- LIN 2.1 Controller (Master and Slave capable); no
crystal required
- Hardware enhanced UART, SMBus™, and
enhanced SPI™ serial ports
- Four general purpose 16-bit counter/timers
- 16-Bit programmable counter array (PCA) with six
capture/compare modules and enhanced PWM
functionality
Clock Sources
- Internal 24 MHz with ±0.5% accuracy master LIN
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
