STMicroelectronics ST7FLIT10BF1M6

Overview

ST7FLIT10BF1M6 from STMicroelectronics is an 8-bit Flash microcontroller featuring 2 KB single-voltage XFlash program memory, 256 bytes RAM, 128 bytes data EEPROM with 300K write/erase cycles, 10-bit ADC with integrated op-amp, SPI interface, and five timers-including two 12-bit auto-reload timers with four PWM outputs-targeting low-power embedded control in industrial sensors and motor drive interfaces.

For engineers reviewing the ST7FLIT10BF1M6 datasheet, ST7FLIT10BF1M6 pinout, ST7FLIT10BF1M6 application, or ST7FLIT10BF1M6 equivalent, key selection criteria include its 2.7–5.5 V operating range, 8 MHz max CPU frequency (with PLL x4/x8), 17 I/O lines with 7 high-sink (20 mA) outputs, and support for five power-saving modes including Halt and Auto Wake-up from Halt.

Technical Context

The ST7FLIT10BF1M6 implements an enhanced ST7 8-bit core with 63 instructions, true bit manipulation, and 17 addressing modes. Its peripheral set includes a configurable watchdog timer, dual 12-bit auto-reload timers supporting input capture and pulse generation, and a 10-bit ADC with fixed-gain op-amp enabling precise analog sensing across 0–430 mV (13-bit effective) and 430 mV–5 V (10-bit) ranges at 5 V VDD.

Clock management integrates an internal 1% RC oscillator, external crystal/ceramic resonator or clock input, optional PLL (x4/x8) for 4/8 MHz internal clocks, and a dedicated 32-MHz input for auto-reload timer timing. Reset and supply supervision feature enhanced LVD for main supply and auxiliary voltage detector (AVD) with interrupt capability for safe power-down sequencing.

FAQ

What is the maximum operating frequency of the ST7FLIT10BF1M6?

The ST7FLIT10BF1M6 achieves up to 8 MHz CPU frequency using either an external 16 MHz crystal with internal divide-by-2, or the internal 1% RC oscillator combined with PLL ×4 (for 4 MHz) or ×8 (for 8 MHz). Electrical characteristics guarantee stable operation across –40°C to +85°C at 2.7–5.5 V supply.

Does the ST7FLIT10BF1M6 support in-application programming (IAP)?

Yes, the ST7FLIT10BF1M6 supports full In-Application Programming of its 2 KB XFlash memory via the ICC interface. Firmware can reprogram designated Flash sectors while executing from other memory regions, enabling over-the-air updates and dynamic parameter storage without halting system operation.

How many analog input channels does the integrated ADC support?

The ST7FLIT10BF1M6 features a 10-bit successive-approximation ADC with seven dedicated analog input channels (AIN0–AIN6) mapped to PB0–PB6. It includes an integrated fixed-gain op-amp that extends effective resolution to 13 bits for signals between 0 and 430 mV when VDD = 5 V.

Can the ST7FLIT10BF1M6 operate from a single 3.3 V supply?

Yes, the ST7FLIT10BF1M6 operates across 2.7–5.5 V, making it fully compatible with 3.3 V systems. All I/O pins are 5 V tolerant when configured as inputs, and the internal voltage reference and ADC maintain specified accuracy across this entire supply range without external level-shifting components.
