ATSAML10D15A-YF Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory, and programmable peripherals. The Cortex-M23 core is an Armv8-M Baseline architecture designed for energy-efficient deterministic embedded computing, sitting within the broader hierarchy of Cortex-M microcontrollers -> 32-bit MCUs -> microcontrollers -> embedded ICs. The SAM L10 family is purpose-built for battery-powered IoT endpoints where deep-sleep current and active-mode efficiency directly determine battery life.
Key features of the ATSAML10D15A-YF include a 32KB Flash program memory (32K x 8), 8KB SRAM, an enhanced Peripheral Touch Controller (PTC), multiple SERCOM serial communication interfaces, a 12-bit ADC, a 10-bit DAC, an operational amplifier, and an analog comparator. The device operates from 1.62V to 3.63V supply and integrates an ISO7816 smart card interface and Event System for inter-peripheral signalling without CPU intervention.
At the architecture level, the device leverages the Cortex-M23's single-cycle IO port, hardware single-cycle multiplier, and TrustZone-M for optional secure firmware partitioning. The integrated PTC supports capacitive touch sensing with driven shield and moisture rejection, eliminating external touch ICs in user-interface designs.
Typical applications include battery-powered IoT sensor nodes, wearable health monitors, secure smart-card readers, capacitive touch user interfaces, and home automation endpoints. The 24-pin SSOP package supports compact through-hole-style PCB layouts where 0.65mm pitch QFN footprints are undesirable for hand-rework or low-density boards.
When designing, prioritise low quiescent current paths - disable unused SERCOM blocks, use sleep walking instead of polling, and confirm the PTC scan rate matches your touch response target. A 100nF decoupling cap must be placed within 5mm of the VDD pin to meet the datasheet noise specification.

Aplicações típicas
ATSAML10D15A-YF é adequado para 7 aplicaçãos: Battery-Powered IoT Sensor Node, Wearable Health Monitor, Capacitive Touch User Interface, ISO7816 Smart Card Reader, Home Automation Endpoint, Industrial Sensor Transmitter, Secure IoT Edge Node.
Battery-Powered IoT Sensor Node
The ATSAML10D15A-YF is purpose-built for battery-powered IoT sensor endpoints. Its < 25 uA/MHz active current and < 100 nA sleep current allow multi-year operation from a single CR2032 coin cell. The Cortex-M23 core's single-cycle IO and hardware multiplier let the MCU wake, sample, transmit via SERCOM, and return to deep sleep within microseconds. Placed directly on a 3V coin cell with a 100nF decoupling cap, the part eliminates external LDO stages and lets the firmware use sleep walking for sub-100 nA average consumption.
Recomendado
Wearable Health Monitor
Wearables demand sub-100 nA quiescent current to preserve battery life during idle periods. The ATSAML10D15A-YF integrates a 12-bit ADC, 10-bit DAC, op-amp, and analog comparator on-chip, allowing direct interface to biometric sensors without external signal conditioning. Its Cortex-M23 core executes DSP-like FIR filters for heart-rate estimation while consuming under 25 uA/MHz. Housed in a compact 24-SSOP package, it suits wristband PCBs where component height is constrained.
Recomendado
Capacitive Touch User Interface
The ATSAML10D15A-YF's integrated Peripheral Touch Controller (PTC) supports up to 24 capacitive touch channels with driven shield and moisture rejection - eliminating an external touch IC. Combined with the Cortex-M23's deterministic response time, the device delivers sub-10ms touch latency in button, slider, and wheel topologies. The 1.62V-3.63V supply range also enables direct operation from 2x AA cells, common in kitchen appliances and remote controls.
Recomendado
ISO7816 Smart Card Reader
The ATSAML10D15A-YF integrates an ISO7816 smart card interface on-chip, supporting Class A/B/C cards at 1.8V, 3V, and 5V signalling levels through external level shifters. The Cortex-M23 core handles T=0 and T=1 protocol stacks within its 32KB Flash budget, while 8KB SRAM buffers command/response APDUs. The Event System enables hardware-driven smart card insertion detection without CPU polling, dropping system current into deep sleep.
Recomendado
Home Automation Endpoint
Home automation hubs and endpoints require both low standby power and responsive user interaction. The ATSAML10D15A-YF balances these with 100 nA sleep current and fast Cortex-M23 wake-up, plus integrated PTC for wall-switch touch panels. Multiple SERCOM interfaces handle concurrent Wi-Fi co-processor links and sub-GHz radio control, while the 12-bit ADC reads environmental sensors. The 24-SSOP package simplifies hand-rework in field-replacement scenarios.
Recomendado
Industrial Sensor Transmitter
Industrial 4-20mA loop-powered transmitters benefit from the ATSAML10D15A-YF's wide 1.62V-3.63V supply range and integrated 12-bit ADC for direct sensor signal conditioning. The Cortex-M23 core executes calibration and linearisation algorithms in 32KB Flash, while 8KB SRAM holds sample buffers. The op-amp and analog comparator on-chip eliminate external signal chains, reducing BOM cost and improving long-term reliability in harsh environments.
Recomendado
Secure IoT Edge Node
Edge nodes collecting sensitive telemetry benefit from the ATSAML10D15A-YF's Cortex-M23 TrustZone-M extensions for optional secure firmware partitioning. The 32KB Flash holds secure + non-secure images, and 8KB SRAM supports encrypted message buffers. The Event System enables hardware-accelerated crypto offload signalling. For higher-security deployments, upgrade to the SAM L11 variant which adds a hardware crypto accelerator without changing the pinout.

Principais diferenciais

- Adds hardware crypto without changing pinout (vs ATSAML11D15A)
Notas de projeto
Estimated: at 32MHz active mode, the ATSAML10D15A-YF draws roughly 25 uA/MHz = 800 uA total. In deep sleep (< 100 nA), average current depends on duty cycle. For a sensor sampling every 10 seconds with 1ms active time, average current is approximately (800 uA * 0.001s / 10s) + 100 nA ≈ 180 nA - well within coin-cell capability. Always place a 100nF X7R decoupling capacitor within 5mm of the VDD pin per the SAM L10 datasheet reference designs.
The 24-SSOP package has a 0.65mm pitch - hand-solderable but tight for inspection. Use a 4-layer PCB with a dedicated ground pour under the device to provide thermal relief and reduce EMI on the PTC sense lines. Keep PTC traces short and away from switching nodes; each centimetre of PTC trace adds parasitic capacitance that can desensitize the touch threshold.
Do not exceed 3.63V on VDD - the Cortex-M23 core is rated 1.62V-3.63V and over-voltage will trigger the internal brown-out detector (BOD) or cause permanent damage. When migrating from the ATSAML10D14A-MF, the firmware image must fit within 16KB Flash (versus 32KB on the -D15) - check linker map files after porting. Also disable unused SERCOM blocks in software to avoid phantom current draw from floating peripherals.
