Detailed Description

32-bit ARM Cortex-M0+ microcontroller running up to 48 MHz, with 128 KB Flash and 16 KB SRAM, in a 64-TQFP (10 x 10 mm) package. Operates from 2.7 V to 5.5 V, supports 52 I/O pins, and integrates key safety and reliability blocks (BOD, POR, WDT) plus DMA. Features a 12-bit ADC (13 channels), internal oscillator, and flexible serial interfaces including I2C, LIN bus, SPI, and UART/USART. Part of the Microchip SAM C20 series (base PN ATSAMC20).

Key Features

Core and performance

- ARM Cortex-M0+ 32-bit CPU up to 48 MHz

- Internal oscillator (no external crystal required for many uses)

Memory

- 128 KB Flash (128K x 8)

- 16 KB SRAM (16K x 8)

I/O and peripherals

- 52 programmable I/O pins

- 12-bit ADC with 13 input channels

- DMA controller for fast, low-CPU data movement

- Watchdog Timer (WDT), Power-On Reset (POR), Brown-out Detect/Reset (BOD)

Connectivity

- I2C (often listed as IC), LIN bus, SPI, UART/USART

Power and operating range

- 2.7 V to 5.5 V supply range

- -40°C to +85°C ambient operating temperature (TA)

Package

- 64-TQFP, 10 x 10 mm body size

- Tape & Reel packing option for automated assembly

Series and compatibility

- SAM C20 family (base number ATSAMC20) for easy migration across densities and packages

Key Advantages

5 V-capable MCU for robust noise immunity and direct interfacing with many sensors and actuators

Low-power Cortex-M0+ core and internal oscillator reduce BOM and simplify designs

Rich serial options (I2C, LIN, SPI, UART/USART) make it easy to connect to sensors, modules, and automotive LIN nodes

Integrated safety features (BOD, WDT, POR) improve system reliability with minimal extra components

DMA and 12-bit ADC improve throughput and measurement fidelity while freeing CPU time

64-pin TQFP with 52 I/O gives ample pins for complex control and HMI tasks

Part of a scalable family, easing code reuse and future upgrades

Packaging

Packing type: Tape & Reel (TR) for high-volume automated placement

Package/case: 64-TQFP

Body size: 10 x 10 mm nominal

Pin count and arrangement: 64 gull-wing leads around the perimeter; typical lead pitch 0.5 mm (confirm in datasheet)

Mounting: Surface Mount (SMT)

Pin allocation: Up to 52 GPIO; remaining pins for power, ground, and dedicated functions (see pinout in datasheet)

Thermal characteristics: -40°C to +85°C TA; actual thermal performance depends on PCB layout and airflow (see thermal data in datasheet)

Electrical characteristics relevant to package use: 2.7 V to 5.5 V operating supply; use proper decoupling on all VDD pins; follow ESD and moisture handling guidelines per datasheet and MSL labeling

Lifecycle

Status: Active production (as of current information). Not near end-of-life based on publicly available data.

Equivalent or alternative models within the family and nearby families:

- ATSAMC20J16A series variants – Same family, 64-pin J package, lower Flash density (useful for cost optimization)

- ATSAMC20J18A series variants – Same family, 64-pin J package, higher Flash density (for larger code)

- ATSAMC21J17A series variants – Similar 64-pin J family with added features such as CAN (check needs and pin compatibility)

- ATSAMD20J17A / ATSAMD21J17A – 3.3 V-centric alternatives with similar peripherals (verify supply voltage needs and pinout)

- Packaging variations of the same device (tray vs tape-and-reel) may exist under close part-number suffixes
