Analog Peripherals - 10-Bit ADC
• Up to 500 ksps • Built-in analog multiplexer with single-ended and
differential mode
• VREF from external pin, internal reference, or VDD • Built-in temperature sensor • External conversion start input option - Two comparators - Internal voltage reference - Brown-out detector and POR Circuitry 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
Voltage Supply Input: 2.7 to 5.25 V - Voltages from 2.7 to 5.25 V supported using On-Chip
Voltage Regulators High Speed 8051 μC Core - Pipelined instruction architecture; executes 70% of
instructions in 1 or 2 system clocks
- Up to 48 MIPS operation
- Expanded interrupt handler
