Product details
Overview
M0L1305QDYYRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified 32-bit Arm® Cortex®-M0+ microcontroller operating up to 32 MHz, featuring 32 KB flash, 4 KB SRAM, a 12-bit 1.68-Msps ADC with 6 external channels, two zero-drift chopper op-amps, and 13 GPIOs - deployed in compact 16-pin SOT (DYY) packages for space-constrained body electronics modules.
For engineers reviewing the M0L1305QDYYRQ1 datasheet, M0L1305QDYYRQ1 pinout, M0L1305QDYYRQ1 application, or M0L1305QDYYRQ1 equivalent, key selection considerations include its -40°C to +125°C operation, 1.62–3.6 V supply range, STANDBY mode consuming 1.0 µA with 32-kHz timer active, and integrated analog signal chain for sensor interface and motor control feedback in automotive interior systems.
Technical Context
The M0L1305QDYYRQ1 implements an Arm Cortex-M0+ core with on-chip SYSOSC (±1.2% accuracy, 4–32 MHz) and LFOSC (±3%, 32 kHz), eliminating external crystals. Its analog subsystem integrates a configurable 1.4-V/2.5-V internal VREF, programmable-gain OPA stages (1–32×), and a high-speed comparator with 8-bit DAC and 32-ns propagation delay - all accessible via shared analog routing resources.
Digital peripherals include two UARTs (one LIN-capable), two I²C interfaces (one FM+, SMBus/PMBus), one SPI (16 Mbps), four 16-bit timers supporting 8 PWM outputs, and a 3-channel DMA controller. Low-power operation is enforced through RUN (71 µA/MHz), STOP (44 µA at 32 kHz), STANDBY (1.0 µA), and SHUTDOWN (61 nA) modes with sub-µs wakeup latency.

FAQ
What is the maximum operating frequency of the M0L1305QDYYRQ1?
The M0L1305QDYYRQ1 features an Arm Cortex-M0+ CPU with a maximum operating frequency of 32 MHz, supported by an internal SYSOSC with ±1.2% accuracy across -40°C to +125°C. This frequency enables deterministic real-time execution of automotive control loops without requiring external crystal oscillators.
Does the M0L1305QDYYRQ1 support LIN communication?
Yes, the M0L1305QDYYRQ1 supports LIN communication via UART0 or UART1, both of which include hardware features enabling LIN 2.2A compliance - including break detection, sync field handling, and checksum calculation. The device's 5-V-tolerant open-drain I/Os simplify direct connection to LIN transceivers.
How many analog-to-digital converter (ADC) input channels does the M0L1305QDYYRQ1 provide?
The M0L1305QDYYRQ1 provides 6 external ADC input channels (A0–A5) in its 16-pin SOT package, consistent with the pin-limited configuration documented in the Device Comparison table. This differs from higher-pin-count variants (e.g., RHB with 10 channels) due to physical I/O constraints.
What low-power modes are available on the M0L1305QDYYRQ1, and what is the lowest current consumption?
The M0L1305QDYYRQ1 supports RUN, STOP, STANDBY, and SHUTDOWN modes. Its lowest active-retention mode is STANDBY at 1.0 µA (with 32-kHz timer running and full SRAM/register retention), and SHUTDOWN consumes 61 nA with IO wakeup capability - critical for battery-powered automotive modules requiring multi-year standby.
Is the M0L1305QDYYRQ1 qualified for automotive applications?
Yes, the M0L1305QDYYRQ1 is AEC-Q100 qualified for automotive applications (Grade 1: –40°C to +125°C ambient temperature), with functional safety documentation available to support ISO 26262 system-level development.
