ATSAML11E15A-MUKPH - Cortex-M23 32KB MCU 32VQFN TrustZone | Microchip
MPN: ATSAML11E15A-MUKPH ✓ Hoạt độngATSAML11E15A-MUKPH Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a processor core, program memory, data memory, and peripherals. The Cortex-M23 belongs to the ARM Cortex-M family of energy-efficient processors designed for embedded applications; ARM TrustZone for ARMv8-M adds hardware-isolated secure and non-secure execution domains. The L11 series sits within Microchip's SAM family of Cortex-M based microcontrollers and competes in the broader low-power MCU market alongside parts such as the STM32L0 and EFR32 families.
Key features include a 32 MHz core, 1.62 V to 3.63 V operating voltage range, integrated 12-bit ADC, 10-bit DAC, SERCOM peripherals, and a hardware cryptographic accelerator supporting AES, SHA, and True Random Number Generator. The KPH (Key-Provisioned Hardware) variant ships pre-loaded with a Trustonic Root of Trust key, enabling immediate use with Kinibi-M SDK and Secure Thingz Secure Deploy architectures. Operating temperature range is -40 °C to +85 °C for the standard grade and -40 °C to +125 °C for the extended grade.
The device is built around a single-cycle I/O capable Cortex-M23 core with a 4-stage pipeline and tightly coupled SRAM, achieving 1.27 DMIPS/MHz while retaining deterministic interrupt response. TrustZone-M hardware isolates secure firmware from the rich OS or application environment, and secure boot verifies signed firmware before execution. The part is supplied in a 32-pin VQFN package with an exposed thermal pad, 5 mm × 5 mm body, and 0.5 mm pitch for compact, reflow-solderable designs.
Typical applications include IoT end nodes with secure cloud onboarding, smart locks and access control, sensor hubs requiring tamper detection, secure payment terminals, and asset-tracking devices that need authenticated firmware updates. The combination of sub-100 nA sleep current and TrustZone-M makes it well suited to battery-powered products that demand a hardware root of trust.
When designing with this part, note that the KPH variant uses a different provisioning flow than the standard MU variant; firmware must call the Kinibi-M SDK to access the pre-provisioned key. The exposed pad must be soldered to a sufficient copper pour for thermal dissipation and electrical grounding; insufficient thermal pad solder can raise junction temperature by tens of degrees at full CPU load.

Ứng dụng tiêu biểu
ATSAML11E15A-MUKPH phù hợp cho 6 Áp dụngs: Secure IoT Sensor Nodes, Smart Locks and Access Control, Wearable Health Monitors, Industrial Sensor Hubs with Tamper Detection, Secure Payment Terminals and POS, Asset Tracking and Fleet Management.
Secure IoT Sensor Nodes
The ATSAML11E15A-MUKPH suits battery-powered IoT sensor nodes because of its sub-100 nA sleep current and TrustZone-M hardware isolation. Its 32 KB Flash and 8 KB SRAM are sufficient for sensor aggregation, BLE control via external radio, and secure cloud onboarding with TLS 1.2 handshakes. The pre-provisioned Trustonic root-of-trust key enables authenticated boot and encrypted firmware updates without external secure elements, lowering BOM cost.

Smart Locks and Access Control
Smart locks demand hardware-rooted security and years of battery life. The ATSAML11E15A-MUKPH delivers both: TrustZone-M isolates credential storage from application code, while the sub-25 µA/MHz active consumption allows coin-cell operation for 3-5 years. The Cortex-M23 core handles BLE pairing, motor control PWM, and tamper detection interrupts, and the pre-provisioned Trustonic key supports secure boot required by Matter and Thread certification.
Được đề xuất
Wearable Health Monitors
Wearable health monitors require low power, secure data handling, and a small PCB footprint. The ATSAML11E15A-MUKPH provides sub-100 nA sleep current that preserves battery life between measurement cycles, plus TrustZone-M that protects patient health data and authenticates the device to mobile apps. The 32-VQFN 5x5 mm package fits inside wristbands and patches, while the integrated 12-bit ADC reads optical heart-rate sensors directly.

Industrial Sensor Hubs with Tamper Detection
Industrial sensor hubs benefit from the ATSAML11E15A-MUKPH chip-level tamper resistance and secure key storage. The chip detects enclosure opening via tamper pins and erases sensitive keys on intrusion. The 32 MHz Cortex-M23 with 8 KB SRAM aggregates multiple sensor buses (I2C, SPI, UART) through configurable SERCOMs, and the industrial -40 °C to +85 °C operating range supports factory and outdoor deployments.
Secure Payment Terminals and POS
The ATSAML11E15A-MUKPH fits PCI PTS-certified payment terminals thanks to its hardware-isolated secure domain and pre-provisioned Trustonic key, which satisfy secure-boot and key-storage requirements. The Cortex-M23 core performs encrypted PIN entry, while SERCOM peripherals interface with NFC readers, thermal printers, and keypads. Sub-100 nA sleep extends battery life in mobile POS units between transactions.
Được đề xuất
Asset Tracking and Fleet Management
Asset trackers and fleet telematics units leverage the ATSAML11E15A-MUKPH for secure firmware authenticity and multi-year battery operation. The MCU wakes periodically from sub-100 nA sleep to acquire GPS or cellular fixes, then returns to sleep. TrustZone-M prevents firmware tampering, which is critical when tracking high-value cargo. The 32 KB Flash stores positioning firmware plus over-the-air update staging area for cellular modules.

Ghi chú thiết kế
Estimated: Active current at 32 MHz with all peripherals enabled is approximately 25 µA/MHz × 32 MHz ≈ 800 µA plus peripheral contribution; sleep current drops below 100 nA with RTC running. Place a 1 µF X7R ceramic bypass capacitor within 2 mm of each VDD pin, and a 10 µF bulk capacitor near the VDDIO pin. Use the on-chip voltage regulator's Low-Power mode for sleep states to achieve the sub-100 nA target.
The 32-VQFN package relies on the exposed thermal pad for heat removal. Solder the EP to a ground copper pour with at least 25 mm² of copper on top layer and stitched thermal vias to inner ground planes. Without proper EP soldering, junction temperature can rise 15-25 °C above ambient at full 32 MHz operation, potentially triggering thermal throttling in industrial environments approaching +85 °C.
Keep SWD traces (PA14/PA15) under 50 mm total length and route them away from switching power nodes. Place a 100 nF decoupling capacitor adjacent to each SERCOM pair used for high-speed SPI to suppress ground bounce. Avoid routing the RESET line near RF traces or antenna feed lines to prevent spurious resets during transmit bursts. Use a 4-layer PCB with continuous ground plane beneath the MCU for best EMI performance.
Do not skip bootloader entry via PA27 low during reset if secure firmware update is required. The KPH variant requires the Kinibi-M SDK call sequence for key access; calling key APIs before SDK initialization returns zeroized data. Verify that your firmware image is signed with the matching Trustonic public key before deployment, otherwise the secure boot sequence rejects the image and the MCU halts at startup.
