Detailed Description

32-bit ARM Cortex-M0+ microcontroller from the SAM C20 series. 128KB FLASH, 16KB RAM, up to 48MHz, 64-pin TQFP (10x10mm). 52 GPIO. 12-channel 12-bit ADC. Built-in brown-out detect/reset, DMA, POR, and watchdog. Operates from 2.7V to 5.5V. Internal oscillator. -40°C to +105°C operating temperature. RoHS3 compliant. Tape & Reel.

Key Features

Core: ARM Cortex-M0+, 32-bit single-core, up to 48MHz

Memory: 128KB FLASH, 16KB RAM

I/O: 52 general-purpose pins

Analog: 12-channel 12-bit ADC

Peripherals: DMA, watchdog (WDT), brown-out detect/reset (BOD), power-on reset (POR)

Connectivity: LIN bus, SPI, UART/USART, I2C (listed as “IC” in source parameters)

Supply voltage: 2.7V to 5.5V (5V-capable designs)

Oscillator: Internal

Package: 64-TQFP (10x10mm), surface mount

Temperature range: -40°C to +105°C (TA)

Compliance: RoHS3

Key Advantages

5V operation supports legacy and industrial ecosystems without level shifting

Low-power Cortex-M0+ core with efficient performance at 48MHz

Rich peripheral set for real-time control and communication

Internal oscillator simplifies BOM and reduces cost

Broad operating temperature for harsh environments

Mature SAM C20 platform with wide tooling and community support

Packaging

Type: Tape & Reel (TR) for automated assembly

Package case: 64-TQFP, 10x10mm body

Mounting: Surface mount, gull-wing leads on four sides

Pin configuration: 64 leads; 52 configurable GPIO; multiple VDD/VSS pins; peripheral functions multiplexed across pins (see datasheet pinout for exact mapping)

Material: Industry-standard molded epoxy package with leadframe; RoHS3 compliant lead finish

Thermal characteristics: -40°C to +105°C operating. Thermal performance depends on PCB copper area and vias; follow datasheet and layout guidelines for heat dissipation

Electrical properties: 2.7V–5.5V supply, 48MHz max system clock, 12-bit ADC, integrated reset and watchdog features. Full electrical limits (current, timing, ESD, IO levels) in the datasheet

Lifecycle

Status: Active as of our latest information. Not near discontinuation

Current stock: 0 units listed. Availability changes frequently; request a quote for lead time and allocation

Alternatives and near-equivalents:

- ATSAMC20J16A (64KB FLASH, same SAM C20 family, 64-pin TQFP; often pin-compatible with lower memory)

- ATSAMC20J18A (256KB FLASH, same family, 64-pin TQFP; higher memory option)

- ATSAMC21J17A (similar 5V-capable Cortex-M0+ with added CAN capability; 64-pin options available; check pinout differences)

- ATSAMD21J17A (similar Cortex-M0+ feature set; typically 1.62–3.3V range, not 5V; review power domain needs)

Note: Verify pin compatibility, electrical limits, and peripheral mapping against your design. If you need exact drop-in or automotive-grade variants, contact our sales team via the Y-IC website for the latest cross-references and guidance
