Pinout

Pin Name Type Function
1 P0.15/P1.0 bidirectional Shared pin combining P0.15 and P1.0. P0.15 alt-functions: EXTI, MCPWM_CH0P, UART0_TX(RX), SPI_DI(DO), SDA, TIM0_CH0, ADC_TRIG1, CMP0_IN. P1.0 alt-functions: WK, MCPWM_CH0N, UART0_TX(RX), SPI_DI(DO). Internal 10 kΩ software-controllable pull-up to AVDD.
2 P2.7 bidirectional P2.7 with alt-functions ADC_CH11 / OPAx_OUT / LDO15 output. Internal 10 kΩ software-controllable pull-up.
3 P1.4 bidirectional P1.4 with alt-functions LRC (64 kHz RC clock output) / MCPWM_CH0P (motor PWM channel 0 high-side).
4 P0.1/P1.5 bidirectional Shared pin. P0.1: wake-up / EXTI / general-purpose IO. P1.5: HRC (4 MHz RC clock output) / MCPWM_CH0N (motor PWM channel 0 low-side).
5 P1.6 bidirectional P1.6 / MCPWM_CH1P (motor PWM channel 1 high-side).
6 P1.7 bidirectional P1.7 / MCPWM_CH1N (motor PWM channel 1 low-side).
7 P1.8 bidirectional P1.8 / MCPWM_CH2P (motor PWM channel 2 high-side).
8 P1.9 bidirectional P1.9 / MCPWM_CH2N (motor PWM channel 2 low-side).
9 P1.14 bidirectional P1.14 / OPA0_IP (op-amp 0 non-inverting input).
10 P1.15/P2.9 bidirectional Shared pin. P1.15: OPA0_IN (op-amp 0 inverting input). P2.9: SPI_DI(DO) / IIC SCL / ADC_CH9 / CMP0 non-inverting input channel 0 (CMP0_IP0). Internal 10 kΩ software-controllable pull-up. Note: internally ADC_CH9 samples OPA2 output when OPA remap is active - software must disable OPA remap to use ADC_CH9 directly.
11 P0.9 bidirectional P0.9 / OPA1_IN (op-amp 1 inverting input).
12 P0.10 bidirectional P0.10 / OPA1_IP (op-amp 1 non-inverting input).
13 P2.1/P2.3 bidirectional Shared pin. P2.1: SPI_CLK / ADC_CH8 / CMP1 non-inverting input 0 (CMP1_IP0). P2.3: CMP1_OUT / voltage reference (REF) / MCPWM_BKIN0 (PWM brake) / SPI_CS / TIM0_CH1. Internal 10 kΩ software-controllable pull-up. Note: ADC_CH8 samples OPA2 output when OPA remap is active on 051 - check remap register.
14 P2.4 bidirectional P2.4 with alt-functions CMP0_OUT / HALL_IN0 (Hall sensor A input) / MCPWM_CH2P (PWM ch2 high-side) / UART1_TX(RX) / TIM1_CH0 / ADC_TRIG3 / CMP1_IP1. Internal 10 kΩ software-controllable pull-up.
15 P2.5 bidirectional P2.5 with alt-functions CMP1_OUT / HALL_IN1 (Hall sensor B input) / MCPWM_CH2N (PWM ch2 low-side) / UART1_TX(RX) / TIM1_CH1 / ADC_TRIG0 / CMP1_IP2. Internal 10 kΩ software-controllable pull-up.
16 P2.6/P2.13 bidirectional Shared pin. P2.6: HALL_IN2 (Hall sensor C input) / MCPWM_CH3P / TIM3_CH0 / ADC_TRIG1 / CMP1_IP3. P2.13: SWCLK (SWD clock) / MCPWM_CH3N / UART0_TX(RX) / IIC SCL / TIM3_CH1. Internal 10 kΩ pull-up (fixed on the SWCLK pad).
17 P2.0 bidirectional P2.0 with alt-functions SWDIO (SWD data) / UART0_TX(RX) / IIC SDA / TIM2_CH1. Internal fixed 10 kΩ pull-up to AVDD.
18 P0.0/P0.2 bidirectional Shared pin. P0.0: WK / EXTI / ADC_CH4 / DAC_OUT (12-bit DAC output). P0.2: RSTN (default function, external reset input) / SPI_DI(DO). Internal 100 kΩ fixed pull-up on RSTN; recommend a 10-100 nF decoupling cap from RSTN to ground (with an optional 10-20 kΩ external pull-up to AVDD, using 100 nF).
19 AVSS power_in System analog/digital ground reference.
20 AVDD power_in Main chip supply input, 2.2-5.5 V. Recommend ≥1 μF decoupling capacitor placed close to the AVDD pin.
21 P2.11/P2.12/P0.11 bidirectional Shared pin combining three die-pads. P2.11: EXTI / MCPWM_CH1P / TIM2_CH0. P2.12: SPI_CS / MCPWM_CH1N / TIM2_CH1 / ADC_TRIG2. P0.11: EXTI / HALL_IN0 / TIM3_CH0 / ADC_CH6 / CMP0_IP1 / IIC SCL. Internal 10 kΩ software-controllable pull-up.
22 P0.12 bidirectional P0.12 with alt-functions EXTI / HALL_IN1 (Hall sensor B input) / TIM3_CH1 / ADC_CH2 / CMP0_IP2 / IIC SDA. Internal 10 kΩ software-controllable pull-up.
23 P0.13 bidirectional P0.13 with alt-functions EXTI / HALL_IN2 (Hall sensor C input) / ADC_CH3 / CMP0_IP3.
24 P0.14 bidirectional P0.14 with alt-functions EXTI / CMP0_OUT / MCPWM_BKIN1 (PWM brake) / UART0_TX(RX) / SPI_CLK / IIC SCL / TIM0_CH1 / ADC_TRIG0 / ADC_CH10 / CMP0_IP4. Internal 10 kΩ software-controllable pull-up.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lks32mc057m6s8.step 315 KB You want the bare part, or you mark your own boards.
lks32mc057m6s8-etched.step 3.9 MB You want the part with LKS32MC057M6S8 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 944 faces against 387 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
