ATSAML10D16A-YF 概要
An ARM Cortex-M23 microcontroller is a 32-bit RISC processor core implementing the Armv8-M baseline architecture with TrustZone-M security. It belongs to the broader hierarchy: microcontroller -> embedded MCU -> semiconductor IC -> ARM Cortex-M family. The Cortex-M23 delivers Thumb-2 instruction set efficiency, deterministic interrupt handling, and optional hardware isolation, making it suitable for secure, low-power IoT endpoints.
Key features of the ATSAML10D16A-YF include an enhanced peripheral touch controller (PTC) supporting driven-shield and mutual-capacitance modes, a 12-bit ADC with up to 20 channels, multiple SERCOM interfaces configurable as UART/SPI/I2C, an ISO7816 smart card interface, and the SAM L10 SleepWalking peripheral architecture. The device integrates an event system for inter-peripheral signaling without CPU wakeup, achieving deep-sleep current below 100 nA while retaining RTC and RAM state.
Technically, the SAM L10 architecture couples the Cortex-M23 core with a low-power bus matrix, dedicated sleep peripherals, and an on-chip voltage regulator with multiple LDOs. The part supports up to 6 SERCOM, 16 PWM channels, a real-time clock with calendar, and a full-speed USB 2.0 device interface on related variants. TrustZone-M enables secure boot and isolated trusted execution.
Typical applications include battery-powered IoT sensors, secure smart-card terminals, wearable health monitors, HVAC touch-key pads, and energy-harvesting wireless nodes. The integrated PTC eliminates external touch ASICs, and the SleepWalking peripherals allow event-driven wakeup from deep sleep without continuous CPU polling.
When designing, prioritize the SSOP-24 thermal pad layout, route the PTC shield traces with careful guarding, and follow the datasheet SleepWalking configuration sequence to achieve the datasheet's sub-100 nA standby current. TrustZone-M configuration must be locked before deploying production firmware.

主な用途
ATSAML10D16A-YF の用途: 6 件s: Battery-Powered IoT Sensor Nodes, Smart Card / ISO7816 Reader Terminals, Capacitive Touch Keypads and Human-Machine Interfaces, Wearable Health and Fitness Devices, Industrial HVAC and Building Automation, Secure IoT Edge Devices with TrustZone-M.
Battery-Powered IoT Sensor Nodes
The ATSAML10D16A-YF's sub-25 uA/MHz active and sub-100 nA sleep currents make it ideal for coin-cell or energy-harvesting IoT sensor nodes. Its SleepWalking peripherals wake the Cortex-M23 core only on valid sensor events, allowing years of operation from a single CR2032 cell. Integrated 12-bit ADC, multiple SERCOM, and TrustZone-M secure boot cover typical environmental-monitoring and asset-tracking node requirements without external security ICs.

設計ノート
To achieve the datasheet's sub-100 nA sleep current on the ATSAML10D16A-YF, place a 100 nF ceramic decoupling capacitor within 2 mm of the VDD pin and a 4.7 uF bulk capacitor on VDDIO. Disable unused peripherals in the PMUX register before entering STANDBY sleep. Use SleepWalking peripherals to keep the ADC or SERCOM in standby state while the CPU remains asleep - this preserves state and avoids expensive wake-up cycles.
The 24-SSOP package has a 0.65 mm pitch; route SWDIO and SWCLK away from switching power traces to avoid debug glitches. Connect all VSS pins to a continuous ground pour on the top layer for thermal and EMI performance. Place the decoupling capacitor loop area under 5 mm^2 to minimize parasitic inductance on high-frequency transients.
Do not assume all SAM L10 SSOP-24 variants share identical firmware images: the ATSAML10D14A has 16 KB Flash and 4 KB RAM, which can cause out-of-memory faults if you replace D16 with D14 without recompiling. Always lock the TrustZone-M security bit before deploying production firmware to prevent post-production security regressions. Verify the boot vector table alignment against the SAM L10 datasheet's 'Memory Map' section.
