ATSAML10D15A-YFT Übersicht
An ARM Cortex-M23 MCU is a 32-bit microcontroller core built on the ARMv8-M Baseline architecture that combines Thumb-2 instruction efficiency with optional TrustZone-M security extensions. Microcontrollers (MCUs) sit at the heart of embedded systems, providing CPU, memory, and peripherals on a single die; the SAM L10 family specifically targets low-power IoT nodes where every microamp of quiescent current translates directly into battery life.
Key features include an enhanced peripheral touch controller (PTC) for capacitive sensing, a 12-bit ADC, a 10-bit DAC, an operational amplifier, analog comparators (AC), multiple SERCOM serial interfaces, ISO7816 smart card interface, and an event system for hardware-triggered inter-peripheral signaling without CPU intervention. The integrated Peripheral Touch Controller supports capacitive buttons, sliders, and proximity sensors without external components.
Architecturally, the device uses a Cortex-M23 core with single-cycle I/O access, a flexible SERCOM block that can be configured as UART, SPI, I2C, or LIN, and a low-power RTC with calendar and alarm functions. The 32KB Flash is organized as 32K x 8 with ECC protection, and the 8KB SRAM is retained across sleep modes. The Cortex-M23 implements the ARMv8-M Baseline instruction set, bringing modern tooling and code density advantages to the Microchip low-power portfolio.
Typical applications include IoT sensor nodes, wearable health and fitness devices, smart-home control panels with touch input, battery-powered remotes, industrial sensors with HMI, ISO7816 smart card readers, and energy-harvesting wireless endpoints using LoRa, BLE, or sub-GHz transceivers. The 24-SSOP package enables compact PCB designs while remaining hand-solderable for prototyping.
When designing with this device, place a 100 nF decoupling capacitor as close as possible to the VDD pin and add a bulk capacitor of at least 1 uF on the main supply rail. Connect unused I/O pins to a defined logic level (VCC or GND) to minimize shoot-through current during deep-sleep cycles. The Cortex-M23 supports Sleep, Deep-Sleep, and Standby modes selectable via the Power Manager, allowing per-application optimization of wake-up latency versus current consumption.

Typische Anwendungen
ATSAML10D15A-YFT ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Nodes, Wearable Fitness and Health Devices, Smart-Home Touch Control Panels, ISO 7816 Smart Card Readers, Industrial Sensor HMI, Energy-Harvesting Wireless Endpoints.
Battery-Powered IoT Sensor Nodes
The ATSAML10D15A-YFT's <100 nA sleep current and <25 uA/MHz active current make it ideal for battery-powered IoT sensor nodes that wake periodically to read sensors and transmit. The 12-bit ADC samples analog sensors while the SERCOM ports drive BLE, LoRa, or Sub-GHz radio transceivers. With 32 KB Flash and 8 KB SRAM, the MCU runs BLE/LoRaWAN stack plus application firmware for years on a single CR2032.
Empfohlen
Wearable Fitness and Health Devices
Wearable fitness and health devices benefit from the ATSAML10D15A-YFT's 32-bit Cortex-M23 DSP performance with sub-100 nA standby, supporting always-on heart-rate and step-count sensing. The integrated operational amplifier and 12-bit ADC capture ECG and bioimpedance signals directly, while the enhanced Peripheral Touch Controller handles swipe-style user input. Battery life easily exceeds two weeks on a small Li-Po cell with the part in deep-sleep between measurements.
Empfohlen
Smart-Home Touch Control Panels
Smart-home touch panels rely on the ATSAML10D15A-YFT's enhanced Peripheral Touch Controller to drive capacitive buttons, sliders, and proximity sensors without external touch ICs, cutting BOM cost. The 32 KB Flash houses the touch firmware and Zigbee/BLE stack, while SERCOM interfaces control LEDs and triac drivers. Energy Star standby compliance is achievable thanks to the <100 nA sleep current drawn between user interactions.
Empfohlen
ISO 7816 Smart Card Readers
ISO 7816 smart card readers leverage the ATSAML10D15A-YFT's integrated ISO 7816 smart card interface, eliminating the need for an external smart card IC. The 32 MHz Cortex-M23 runs protocol T=0/T=1 stacks securely from 32 KB Flash. The 12-bit ADC and analog comparator provide robust line-monitoring for ESD and over-voltage conditions on the card contacts.
Empfohlen
Industrial Sensor HMI
Industrial sensor HMI applications benefit from the ATSAML10D15A-YFT's robust 12-bit ADC, integrated op-amp, and analog comparators providing front-end signal conditioning and threshold detection in a single chip. The Cortex-M23 core drives local capacitive touch interfaces, while SERCOM channels link to RS-485 or CAN transceivers. Wide operating temperature range and <100 nA standby make this device suitable for always-on field instrumentation.
Empfohlen
Energy-Harvesting Wireless Endpoints
Energy-harvesting wireless endpoints using the ATSAML10D15A-YFT achieve self-powered operation by exploiting the <100 nA sleep current, allowing wake-on-interrupt from sub-millisecond piezo-electric or solar harvests. The 32 KB Flash stores small LoRa or BLE firmware images, and the Cortex-M23 wakes the radio only when sensor data and harvested energy are both available. The MCU reliably runs from a 1.5 V or 3.3 V supply rail with no additional LDO required for many sensors.

Wichtigste Unterscheidungsmerkmale
- Industry-leading <100 nA sleep current in a 32-bit Cortex-M23 (vs. ATSAMD20J15A-AN)
- Enhanced Peripheral Touch Controller integrated (vs. ATSAML11D15A-YFT)
- Analog-rich integration (op-amp + DAC + AC) (vs. ATSAML10D15A-YUT)
Designhinweise
Estimated: at VDD = 3.3 V with CPU at 32 MHz active, the ATSAML10D15A-YFT draws about 25 uA/MHz, giving roughly 800 uA in full-speed compute plus sensor SERCOM activity. In Deep-Sleep with RTC running, current drops to under 1.5 uA, and in full Standby with retained SRAM, expect below 100 nA. Decouple VDD with a 100 nF X7R ceramic capacitor placed within 2 mm of the VDD pin to suppress switch-mode ripple that would otherwise pin the part into a higher sleep-current mode.
Route the SWDIO and SWCLK traces as short, matched-length pairs and place a 10 k pull-up on SWDIO during reset to ensure reliable Cortex-M23 debug-port hand-shake. Keep noisy switcher traces away from analog inputs (AIN0 - AIN3) and the integrated op-amp pins to preserve the 12-bit ADC's ENOB specification.
When migrating from SAM D20 Cortex-M0+ firmware, verify the NVIC priority bit count - Cortex-M23 uses 4 priority bits compared to M0+'s 2 bits, which can change pre-emption behavior in ISRs. Also, the Cortex-M23 TrustZone-M bit is OFF on SAM L10 devices, but firmware masking the secure-region on a SAM L11 then re-flashing back to a SAM L10 will lock the device - always erase the entire Flash array before changing security settings.
Compliance-Informationen
RoHS compliant per Microchip product page. AEC-Q100 qualification not specified for the SAM L10 family - choose PIC16F916-I/SO or similar automotive-grade MCUs for automotive applications.
