MC96F1206RBN

The MC96F1206RBN is a CMOS single-chip 8-bit microcontroller based on an M8051-compatible core. It integrates on-chip Flash, SRAM, analog and timing peripherals, and multiple system reliability and power-management features suitable for compact embedded control designs.

With a 6 Kbyte Flash program memory, 256 bytes of internal RAM, an internal RC oscillator and integrated 12-bit ADC with LDO reference, the MC96F1206RBN provides a highly integrated platform for applications that require mixed-signal interfacing, timing control and low-voltage operation across an industrial temperature range.

Key Features

• Core  M8051-compatible 8-bit CISC core with 2 clocks per cycle; minimum instruction execution time 125 ns @ 16 MHz internal RC oscillator.
• Memory  6 Kbytes on-chip Flash (ISP programmable, 10,000 cycle endurance) and 256 bytes internal RAM for compact program and data storage.
• Analog  12-bit A/D converter with 15 input channels and optional internal 2.5 V LDO reference for multi-channel analog signal acquisition at up to 50 ksps.
• Timers and PWM  16-bit timer/counter/PWM functionality plus Basic Interval Timer (8-bit) and Watch Dog Timer (8-bit) for precise timing, PWM control and supervisory timeout functions.
• System Reliability  On-chip Power-On Reset (POR), Low Voltage Indicator (LVI) and Low Voltage Reset (LVR) with selectable reset levels to ensure robust start-up and brownout protection.
• Oscillators  Internal RC oscillator (32 MHz ±5% across –40 to +85 °C) and internal WDT oscillator reduce external component count and simplify clocking.
• Low-Power Modes  Multiple power-down options including STOP1, STOP2 and IDLE modes to reduce power consumption in energy-sensitive designs.
• Peripherals and I/O  18 GPIO pins (P0[7:0], P1[7:0], P2[2:0]), 16-bit CRC/checksum generator and interrupt sources including external pins, timers, WDT, BIT and ADC.
• Operating Range and Packaging  Wide operating voltage 2.2–5.5 V, temperature range –40 to +85 °C, supplied in a 20-TSSOP (173 mil) surface-mount package.

Typical Applications

• Multi-channel analog data acquisition  Use the 12-bit ADC with 15 input channels and internal LDO reference for precise sensor sampling and signal conditioning.
• Timing and motor control  Leverage the 16-bit timer/counter and PWM capabilities for motor drive timing, speed control and general-purpose sequencing.
• Supervisory and safety monitoring  Integrate Watch Dog Timer, POR, LVI and LVR features to implement reliable system supervision and brownout protection.
• Low-power embedded control  Employ STOP and IDLE power modes alongside internal oscillators to minimize external components and reduce standby power.

Unique Advantages

• Highly integrated analog and digital peripherals: 12-bit ADC, internal LDO reference, timers, PWM and CRC generator reduce BOM and simplify board design.
• Compact memory footprint with ISP: 6 Kbytes Flash with in-system programming and 10,000-cycle endurance enables field updates and iterative development.
• Flexible power and reset control: POR, selectable LVR levels and LVI provide layered protection for reliable power-up and brownout handling.
• Internal clocking options: Internal RC oscillator and WDT oscillator minimize the need for external clock components and speed prototype iterations.
• Wide voltage and temperature range: 2.2–5.5 V operation and –40 to +85 °C rating support designs across common industrial conditions.
• Small surface-mount package: 20-TSSOP (173 mil) offers a compact footprint for space-constrained PCB layouts.
