Product details
Overview
M0L1306QRHBRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified 32-bit Arm® Cortex®-M0+ microcontroller operating up to 32 MHz, featuring 64 KB flash, 4 KB SRAM, a 12-bit 1.68-Msps ADC with 10 external channels, two zero-drift chopper op-amps, and integrated temperature sensing - deployed in steering wheel systems and body electronics for real-time sensor signal conditioning and motor control.
For engineers reviewing the M0L1306QRHBRQ1 datasheet, M0L1306QRHBRQ1 pinout, M0L1306QRHBRQ1 application, or M0L1306QRHBRQ1 equivalent, key selection criteria include its -40°C to +125°C operation, 1.62–3.6 V supply range, STANDBY mode consuming 1.0 µA with full SRAM retention and 32-kHz timer, and 32-pin VQFN (RHB) package with 28 GPIOs including two 5-V-tolerant open-drain I/Os.
Technical Context
The M0L1306QRHBRQ1 integrates a high-accuracy ±1.2% internal SYSOSC (4–32 MHz) and ±3% LFOSC (32 kHz), eliminating external crystals while supporting ultra-low-power operation across RUN (71 µA/MHz), STOP (44 µA at 32 kHz), STANDBY (1.0 µA), and SHUTDOWN (61 nA) modes. Its analog subsystem enables direct sensor interfacing via programmable analog routing between ADC, OPAs, COMP, and DAC.
Digital intelligence includes a 3-channel DMA, four 16-bit timers (eight PWM channels total), event fabric signaling, and communication peripherals: two UARTs (one LIN-capable), two I²C (one FM+, SMBus/PMBus), and one SPI (16 Mbit/s), all supporting wakeup from low-power states.
