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
• Low cost, complete development kit

Supply Voltage

• Range: 2.7–3.6 V (50 MIPS) 3.0–3.6 V (100 MIPS)
• Power saving suspend and shutdown modes

High Speed 8051 μC Core

• Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks
• 100 MIPS or 50 MIPS throughput with on-chip PLL
• Expanded interrupt handler
• 2-cycle 16 x 16 MAC engine

Memory

• 1280 bytes internal data RAM (256 + 1024)
• 32 kB (‘F360/1/2/3/4/5/6/7) or 16 kB (‘F368/9) Flash; In-system programmable in 1024-byte Sectors—1024 bytes are reserved in the 32 kB devices

Digital Peripherals

• up to 39 Port I/O; All 5 V tolerant with high sink current
• 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
• Real time clock mode using PCA or timer and external clock source
• External Memory Interface (EMIF)
  

Clock Sources

• Two internal oscillators:
• 24.5 MHz with ±2% accuracy supports crystal-less UART operation
• 80/40/20/10 kHz low frequency, low power
• Flexible PLL technology
• 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

Packages
