ATSAML10D15A-YUT - 32KB Flash Cortex-M23 MCU | Microchip
MPN: ATSAML10D15A-YUT ✓ Hoạt độngATSAML10D15A-YUT Tóm tắt
What is a low-power Cortex-M23 microcontroller? A 32-bit microcontroller is an integrated circuit that combines a CPU core, program memory (Flash), data memory (SRAM), and a set of peripherals on a single die. The Cortex-M23 is Arm's smallest and most energy-efficient TrustZone-capable core, sitting below Cortex-M0+ and Cortex-M3 in the hierarchy: ARM core -> Cortex-M family -> Cortex-M23 -> SAM L10/L11 MCU -> 32-bit low-power microcontroller. The SAM L10 family specifically targets battery-powered applications that need deterministic performance with deep-sleep current below 100 nA.
Key features include less than 25 uA/MHz active mode power consumption, less than 100 nA sleep mode current, an enhanced peripheral touch controller (PTC), multiple SERCOM serial interfaces, a 12-bit ADC, 10-bit DAC, on-chip op-amp, and analog comparators. The integrated ISO7816 smart card interface and event system make it suitable for secure and event-driven designs without CPU wake-ups.
The device is built on a low-leakage process and integrates Arm TrustZone for Cortex-M23, allowing secure and non-secure firmware regions. The peripheral touch controller supports capacitive buttons, sliders, and proximity sensing in noisy environments, while the 12-bit ADC and 10-bit DAC provide sufficient resolution for sensor conditioning and small-signal generation tasks.
Typical applications include IoT sensor nodes, secure wearables, smart card terminals, capacitive touch user interfaces, and battery-powered industrial edge devices. The combination of sub-100 nA sleep current and TrustZone security makes the SAM L10 particularly attractive for always-on sensor endpoints.
When designing with this part, choose the L10 over the L11 only if you do not need the L11's additional crypto accelerators and larger SRAM; both share the same Cortex-M23 core. The 24-SSOP package is footprint-compatible with other SAM L10/L11 24-pin variants.

Ứng dụng tiêu biểu
ATSAML10D15A-YUT phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Node, Capacitive Touch User Interface, Smart Card Terminal (ISO7816), Wearable Fitness Tracker, Industrial Wireless Sensor Node, Secure Smart Lock.
Battery-Powered IoT Sensor Node
The ATSAML10D15A-YUT is ideal for battery-powered IoT sensor nodes because of its industry-leading <100 nA sleep current and <25 uA/MHz active consumption. The 32 KB Flash accommodates typical BLE/Zigbee stack and application code, while 8 KB SRAM handles small sensor buffers. TrustZone isolates secure key storage from the main application, preventing firmware extraction. In a typical deployment, the MCU spends 99% of its time in deep sleep and wakes briefly to read a sensor via the 12-bit ADC and transmit via a SERCOM-configured SPI link to a radio module, achieving multi-year coin-cell battery life.

Capacitive Touch User Interface
The ATSAML10D15A-YUT integrates an enhanced peripheral touch controller (PTC) that supports capacitive buttons, sliders, and proximity sensing without external components. Combined with the on-chip op-amp and 12-bit ADC, the MCU can also read resistive sensors in the same design. The sub-100 nA sleep current means the touch interface remains always-on without draining the battery. The 32 KB Flash is sufficient to host a touch library plus application logic, while the Cortex-M23's deterministic interrupt latency ensures low-latency touch response. Reference designs in the SAM L10 datasheet demonstrate waterproof touch button arrays.

Smart Card Terminal (ISO7816)
The ATSAML10D15A-YUT includes a dedicated ISO7816 smart card interface, eliminating the need for an external UART-to-smart-card bridge IC. The Cortex-M23 core handles the T=0/T=1 protocol stack while TrustZone protects the cryptographic key material. Active mode power under 25 uA/MHz keeps the reader within USB bus-power budgets. The 24-SSOP package provides 24 pins, sufficient for VCC, RST, CLK, I/O, and several GPIOs for status LEDs and user feedback. This MCU is used in point-of-sale terminals, electronic ID readers, and SIM programming tools.

Wearable Fitness Tracker
Wearables require sub-100 nA standby current to achieve multi-day battery life, which the ATSAML10D15A-YUT delivers. The Cortex-M23 core at 32 MHz runs heart-rate, step-counting, and display-update algorithms, while the on-chip DAC drives an LED driver for optical heart-rate sensing. The 12-bit ADC reads battery voltage and motion sensor data through SERCOM-configured I2C/SPI. TrustZone isolates biometric data from general-purpose firmware, meeting emerging privacy requirements. The 24-SSOP package fits inside thin wearable enclosures with a 5.30 mm width and 0.65 mm pitch.

Industrial Wireless Sensor Node
The ATSAML10D15A-YUT suits industrial 4-20 mA loop-powered sensor nodes because of its low active power (<25 uA/MHz) and wide operating temperature range typical of the SAM L10 family. The on-chip op-amp and 12-bit ADC condition 4-20 mA current sense or bridge sensor signals directly, eliminating external analog front-ends. SERCOM interfaces connect to RS-485, LoRa, or WirelessHART transceivers. Industrial users value the deterministic Cortex-M23 interrupt latency for time-critical protocol handling. TrustZone secures calibration constants and prevents field tampering.
Được đề xuất
Secure Smart Lock
Smart locks benefit from the ATSAML10D15A-YUT's TrustZone for Cortex-M23, which isolates credential storage from the application firmware. The <100 nA sleep current enables years of battery life on a coin cell. The enhanced peripheral touch controller supports capacitive keypad entry, while the 10-bit DAC drives a buzzer for feedback. SERCOM interfaces support BLE for smartphone pairing. The integrated ISO7816 interface can read RFID cards for credential authentication. The 24-SSOP package fits inside the limited PCB area of a cylindrical lock body.

Ghi chú thiết kế
The ATSAML10D15A-YUT sleep current of <100 nA is achievable only when unused peripherals are disabled in the PMUX/PMEN registers and the Cortex-M23 is in WAIT or RETAIN sleep mode. Estimated: at 32 MHz active current of 25 uA/MHz, the MCU draws ~800 uA; transitioning to deep sleep between sensor reads reduces average current by 1000x for duty-cycled IoT nodes. Always configure the brown-out detector (BOD33) at the lowest threshold that matches your supply rail to minimize quiescent draw.
Place the 100 nF VDD decoupling capacitor within 3 mm of the VDD pin, with a via to a clean ground plane. Add a 1 uF bulk capacitor near the MCU for the analog supply rail (VDDANA). The 24-SSOP package has a 0.65 mm pin pitch, requiring fine-pitch PCB manufacturing. Route SWDIO and SWCLK away from noisy switching nodes to prevent debug-interface lockups. Expose the RESET pin to a test pad for in-system programming.
Do not assume TrustZone is enabled by default - secure firmware must configure the Security Attribution Unit (SAU) at startup to partition Flash into secure and non-secure regions. Forgetting to configure the SAU leaves the entire device in secure mode and may break non-secure application code. Additionally, the peripheral touch controller (PTC) requires dedicated firmware calibration for the specific PCB overlay material and thickness; reference Microchip application notes for touch tuning.
