Mixed-Signal Byte-Programmable EPROM MCU
Analog Peripherals
- 10-Bit ADC (‘T630/2/4 only)
• Up to 500 ksps
• Up to 16 external inputs
• VREF from on-chip VREF, external pin,
Internal Regulator or V_DD
• Internal or external start of conversion source
• Built-in temperature sensor
- 10-Bit Current Output DAC (‘T630/2/4 only)
- Comparator
• Programmable hysteresis and response time
• Configurable as interrupt or reset source
• Low current (<0.5 µA)
On-Chip Debug
- C8051F336 can be used as code development 
platform; Complete development kit available
- On-chip debug circuitry facilitates full speed, 
non-intrusive in-system debug
- Provides breakpoints, single stepping, 
inspect/modify memory and registers
Supply Voltage 1.8 to 3.6 V
- On-chip LDO for internal core supply
- Built-in voltage supply monitor
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
- 768 Bytes internal data RAM (256 + 512)
- 8, 4, or 2 kB byte-programmable EPROM code
memory
Digital Peripherals
- 17 Port I/O with high sink current capability
- Hardware enhanced UART, SMBus™, and
enhanced SPI™ serial ports
- Four general purpose 16-bit counter/timers
• Timer 3 supports real-time clock using external clock
source
- 16-Bit programmable counter array (PCA) with three
capture/compare modules and enhanced PWM
functionality
Clock Sources
- Two internal oscillators:
• 24.5 MHz with ±2% accuracy supports crystal-less
UART operation and low-power suspend mode with
fast wake time
• 80/40/20/10 kHz low frequency, low power operation
- External oscillator: RC, C, or CMOS Clock
- Can switch between clock sources on-the-fly; useful
in power saving modes
