The Microchip Technology ATSAML21J17B-UUT is an ultra-low-power 32-bit ARM Cortex-M0+ flash microcontroller from the SAM L21J family, featuring 128 KB of Flash and 16 KB of SRAM in a 64-ball WLCSP package (3.58 x 3.28 mm). It operates from a 1.6 V to 3.6 V supply, runs at up to 48 MHz, and is rated for the industrial temperature range of -40C to +85C. According to the Mouser listing and the SAM L21 Family Data Sheet, this device consumes under 35 uA/MHz in active mode and only 200 nA in Sleep mode, making it one of the most energy-efficient Cortex-M0+ MCUs in its class. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (SRAM), and a rich set of peripherals. The ARM Cortex-M0+ is the smallest and most energy-efficient core in the Cortex-M family, optimized for low-power deterministic embedded control. Within Microchip's portfolio, this device sits in the hierarchy: Cortex-M0+ core -> ARM 32-bit MCU -> SAM L21 ultra-low-power family -> Functional Safety (FuSa) product line -> embedded microcontroller. Its combination of Cortex-M0+ simplicity with SleepWalking, power domain gating, and ultra-low-power peripherals targets always-on, battery-powered applications. Key features of the ATSAML21J17B-UUT include 128 KB Flash, 16 KB SRAM, an ARM Cortex-M0+ core at 48 MHz (2.46 CoreMark/MHz), full-speed USB device support, a 12-bit 1 Msps ADC, up to five SERCOM channels, a 32-bit RTC, and PTC (Peripheral Touch Controller) for capacitive touch sensing. The WLCSP64 package enables compact PCB designs, while the integrated power management supports SleepWalking, deep sleep, backup, and standby modes. Functional Safety (FuSa) features assist in safety-critical designs. Architecturally, the SAM L21 family uses a sophisticated power-domain gating scheme that selectively powers only the peripherals in use. This, combined with the Cortex-M0+ two-stage pipeline and the Wake-on-event interrupt controller, minimizes wake-up latency while keeping idle current at 200 nA. The integrated 12-bit DAC, multiple timer/counter channels, and event system allow complex signal routing without CPU intervention. Typical applications include wearable fitness and health devices, battery-powered IoT sensors, smart metering, home automation, remote controls, and ultra-low-power wireless sensor nodes. It is also used in industrial IoT edge nodes where long battery life and a small footprint (WLCSP64) are both essential. When designing with this MCU, designers should pay attention to decoupling (place 100 nF X7R capacitors near each VDD pin), I/O bank voltage reference requirements for analog accuracy, and the need to configure unused pins as outputs with defined levels to minimize leakage. The WLCSP package also demands careful PCB pad design and assembly process control. This page synthesizes distributor pricing, drop-in alternatives drawn from the same SAM L21 family, and practical design notes not found in the manufacturer datasheet, providing engineers a one-stop reference for sourcing the ATSAML21J17B-UUT.

The part is part of the SAM L21 family, Microchip's lowest-power Cortex-M0+ line featuring an on-chip Cortex-M0+ core, single-cycle hardware multiplier, and Micro Trace Buffer for instruction trace. What is a Cortex-M0+ microcontroller? A Cortex-M0+ microcontroller is an ARM Holdings 32-bit microcontroller core optimized for the smallest die area and lowest active power, using a 2-stage pipeline and single-cycle I/O port access. Within the hierarchy, the Cortex-M0+ belongs to the ARM Cortex-M family, itself a subset of the ARMv6-M architecture, and the SAM L21 family is Microchip's ultra-low-power derivative. This places the ATSAML21J18A-MUT in the broad category: microcontroller (MCU) -> 32-bit MCU -> ARM Cortex-M MCU -> ultra-low-power MCU -> semiconductor IC. Key differentiating features include 1.6V to 3.6V supply voltage, integrated full-speed USB 2.0 device with on-chip transceiver, 12-bit 1 MSPS ADC, 10-bit 350 kSPS DAC, four SERCOM channels, six timers, two I2S interfaces, and a PTC (Peripheral Touch Controller) for capacitive touch sensing. The device operates in active, idle, standby, backup, and off sleep modes with wakeup times under 1.5 microseconds, making it ideal for battery-powered applications where microamp sleep currents dominate battery life. Architecturally, the SAM L21 uses a power-efficient design with separate voltage domains for core and I/O, allowing the I/O bank to remain active while the core is in standby. This dual-bank approach, combined with Microchip's proprietary power-management IP, delivers 35 uA/MHz active current and standby currents around 1.7 uA with full RAM retention, which is competitive in the ultra-low-power MCU class. Typical applications include battery-powered IoT sensor nodes, wearable fitness bands, smart-home sensor hubs, low-power wireless sensor networks, and capacitive touch human-machine interfaces. Industrial uses include metering, building automation, and remote controls; consumer uses include toys, gaming peripherals, and personal health devices. Design consideration: when migrating from a SAM D21 part, note that the SAM L21 uses the same SERCOM peripheral but adds a low-power backup domain and a touch controller not present on the SAM D21. Firmware may need to enable the backup domain registers before using RTC or wake-on-touch features. This page consolidates distributor pricing, drop-in alternatives within the SAM L21 family and across the SAM D21 family, and practical low-power design notes beyond the manufacturer datasheet.

ATSAML21J18B-UUT

ATSAML21J18B-UUT - 256KB Flash Cortex-M0+ MCU | Microchip

The Microchip ATSAML21J18B-UUT is an ultra-low-power 32-bit ARM Cortex-M0+ flash microcontroller operating up to 48 MHz, delivering 2.46 CoreMark/MHz while consuming under 35 uA/MHz in active mode and only 200 nA in Sleep mode. It integrates 256 KB of Flash and 40 KB of SRAM in a 64-ball WLCSP package, and operates from a 1.6 V to 3.6 V supply across the industrial temperature range of -40C to +85C. According to the Microchip SAM L21 family datasheet, the device is the highest-density variant of the SAM L21J WLCSP64 line and provides sophisticated power management through power domain gating, SleepWalking, and ultra-low-power peripherals. A microcontroller (MCU) is an integrated circuit containing a processor core, program and data memory, and programmable peripherals. ARM Cortex-M0+ cores target the lowest active power and smallest die area among the Cortex-M family, making them ideal for battery-powered embedded systems. Within that hierarchy the SAM L21 sits in Microchip's ultra-low-power tier alongside the SAM L11 secure family and the SAM D20/D21 mainstream tier, all built around the same ARM Cortex-M0+ instruction set. This particular J18B-UUT part is the WLCSP64 package variant - WLCSP (Wafer Level Chip Scale Package) is the smallest-footprint option of the SAM L21J family and is intended for space-constrained wearables and sensor nodes. Key features include a 12-bit 1 MSPS ADC, a 10-bit DAC, four SERCOM channels that can each be configured as USART, I2C, or SPI, and a 32-bit RTC with calendar mode. Power management is the central design pillar: SleepWalking lets peripherals wake the CPU only when relevant events occur, while six flexible power domains allow unused logic to be powered down at run time. The 64-ball WLCSP package has a footprint of approximately 3.0 x 3.0 mm and a height under 0.5 mm, allowing direct attachment to a top-side PCB layer with minimal inductance. The architecture pairs the Cortex-M0+ core with a 4-channel event system and a Peripheral Touch Controller (PTC) supporting capacitive touch sensing. The 12-bit ADC achieves up to 1 MSPS at full resolution and 2 MSPS at 8-bit resolution, providing enough bandwidth for sensor fusion and audio preprocessing. A hardware cryptographic module is not present on this family - it is delegated to the SAM L11 tier - so security-sensitive designs should add an external secure element. Typical applications include battery-powered IoT sensor nodes, wearable fitness and health devices, smart metering, home automation endpoints, and industrial wireless sensor transmitters. The combination of Cortex-M0+ performance, 256 KB of Flash for application code, and SleepWalking peripheral architecture keeps the average system current below 1 mA in many typical duty-cycled scenarios. When designing with this device, prioritize sleep-mode current draw as your primary figure of merit; idle power dominates battery life more than active throughput. The WLCSP64 footprint requires PCB pad design rules substantially different from QFP or QFN packages - the recommendation is non-solder-mask-defined (NSMD) pads with a diameter roughly 0.4 mm and a pitch matching the package balls. Reference the Microchip SAM L21 WLCSP64 land pattern application note for exact stack-up recommendations.

An ARM Cortex-M0+ microcontroller is a 32-bit RISC processor core designed by Arm that delivers higher code density and energy efficiency than 8/16-bit cores while maintaining a low gate count. It sits within the broader hierarchy of microcontroller -> embedded processor -> SoC -> semiconductor. Microchip's SAM L22 family targets battery-powered and energy-harvesting applications by combining a Cortex-M0+ core with sophisticated power management technologies, on-chip peripherals, and segment LCD driving capability.

As part of the SAM L22G family, it integrates an on-chip segment LCD controller with up to 8x32 segments, making it purpose-built for battery-powered metering, wearable, and segment-LCD display applications. What is a SAM L22 microcontroller? The SAM L22 family sits within Microchip's broader SAM lineup of 32-bit ARM Cortex microcontrollers. A microcontroller (MCU) is a single-chip computer integrating a CPU core, Flash program memory, SRAM data memory, and programmable peripherals. The L22 sub-family is differentiated by its ultra-low-power architecture, segment LCD driver, and Cortex-M0+ efficiency - aimed at deeply embedded applications that must run for years on a single coin cell. In the system hierarchy it occupies the power-management-aware edge of the IoT device spectrum: MCU -> ultra-low-power MCU -> segment LCD MCU -> SAM L22 family. Key differentiating specifications include 39 uA/MHz active current running CoreMark, 490 nA ultra-low-power backup mode with RTC retention, integrated 16-channel 12-bit ADC, four SERCOM interfaces (configurable as I2C/SPI/UART), full-speed USB device with internal pull-up, and a segment LCD controller supporting up to 8x32 segments. The Cortex-M0+ core delivers 0.9 DMIPS/MHz with single-cycle I/O access and an MPU for memory protection. Architecturally, the device uses a Harvard-style bus matrix with separate AHB/APB domains, SleepWalking peripherals that wake only on configured events, and event system for zero-CPU peripheral-to-peripheral signaling. The 32MHz operation is sourced from an internal 32.768kHz oscillator and PLL, eliminating external crystals in many designs. Operating voltage spans 1.6V to 3.6V across -40C to +85C industrial range. Typical applications include battery-powered flow and gas meters, wearable health monitors with segment LCD displays, smart thermostats, electronic shelf labels, IoT sensor nodes with USB diagnostic port, and industrial HMI panels. The on-chip LCD driver eliminates the need for an external segment-driver IC. When designing with this part, route the segment LCD pins as a dedicated bus to minimize crosstalk, place the decoupling capacitor within 2mm of VDDIN, and verify the backup domain RTC crystal load capacitance to achieve the 490 nA standby target.

ATSAML22J18A-MUT - 32MHz Cortex-M0+ MCU 256KB Flash | Microchip

The Microchip ATSAML22J18A-MUT is an ultra-low-power 32-bit ARM Cortex-M0+ microcontroller from the SAM L22 family, integrating 256 KB of Flash and 32 KB of SRAM in a 64-pin QFN (9x9) package with an exposed thermal pad. It operates from 1.6 V to 3.6 V and runs up to 32 MHz, making it suited to battery-powered and energy-harvesting designs where active current, sleep current, and wake-up latency are all constrained. A low-dropout (LDO) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is very close to the output voltage, dropping only the headroom required by a pass element. In a power-management hierarchy, an LDO sits below a DC-DC switching converter and is used for post-regulation or noise-sensitive rails; for the SAM L22 family specifically, internal LDO and DC-DC blocks support sleep-mode currents in the hundreds of nanoamperes. Understanding this hierarchy helps frame why SAM L22 parts are positioned for always-on sensor nodes rather than high-throughput DSP. Key features of the ATSAML22J18A-MUT include 39 uA/MHz active current running CoreMark, 490 nA ultra-low-power backup mode with RTC retention, an on-chip 32.768 kHz RTC, and segment LCD support up to 8x36 segments. The integrated PTC (Peripheral Touch Controller) enables capacitive touch sensing without an external IC, and the SERCOM-configurable serial interfaces provide flexible UART/SPI/I2C connectivity. Hardware crypto, true random number generator, and secure boot features support IoT security requirements. The SAM L22 architecture uses a single-cycle hardware multiplier, single-cycle 32-bit divider option, and a low-power Cortex-M0+ core with Sleepwalking peripherals that wake the CPU only on qualifying events. The device supports 1.62 V minimum supply, allowing direct connection to single-cell Li-ion or 2x AA chemistries without external regulation. Code density is enhanced via Thumb-2 instruction set and Microchip's Atmel Studio/MPLAB X IDE toolchain with FreeRTOS support. Typical applications include IoT sensor nodes, wearable health monitors, smart home hubs with segment LCD front panels, industrial metering, capacitive touch user interfaces, and battery-powered HVAC controls. The 64-QFN with EP provides a compact footprint for space-constrained PCBAs while the exposed pad improves thermal dissipation for sustained 32 MHz operation. When designing with this device, plan decoupling per Section 7 of the manufacturer datasheet, route the exposed pad to a contiguous ground copper pour, and configure the LCD charge pump voltage before driving segments. Use sleep modes strategically - Sleepwalking I/O can reduce average current by 10x or more compared with polling. The VDDIO2 supply rail allows independent I/O voltage for mixed-voltage peripherals.

Technically, the SAM S70 architecture couples an MPU-aware Cortex-M7 core to a multi-layer AHB bus matrix with separate peripherals and tightly-coupled memories, enabling deterministic DMA and zero-wait-state Flash access via a 2 KB cache. 256 KB SRAM is split between system SRAM and backup SRAM retained in certain low-power modes; the 12-bit ADC and analog comparators are routed to dedicated peripheral channels. Hardware crypto is not part of the SAM S70 itself - that feature lives on the related SAME70 family. Typical applications include industrial motor control (BLDC/PMSM), industrial automation and PLC interfaces, building automation and HVAC, smart energy metering, automotive body/infotainment peripherals, audio processing front ends, machine vision at the edge, and connected gateways with Ethernet and CAN-FD. The SAMS70N19 is also used in medical instrumentation where the FPU and DSP extension accelerate filter computations. When designing with this device, allocate sufficient decoupling (100 nF near each VDD/VDDIO pin plus bulk) and follow Microchip's SAMS70 errata for HS USB PHY, EBI timing, and CAN-FD revision items. Use MPLAB X IDE with MPLAB Harmony 3 (csp, core, and a supported middleware layer) for code generation, peripheral drivers, and FreeRTOS integration.

Its peripheral set includes CAN-FD, four I2S ports for audio codec interfacing, an image sensor interface (ISI), a camera interface, and up to 119 GPIOs. Engineering trade-offs include higher dynamic power at 300 MHz than Cortex-M4 parts and a 144-LQFP footprint that requires careful power-plane design. Typical applications span industrial motor control, industrial HMI / TFT panels, point-of-sale terminals, audio amplification systems, automotive infotainment prototyping, building-automation gateways, and IoT edge nodes that demand on-the-fly TLS handshake acceleration via the integrated crypto engine. The wide 3.0V to 3.6V supply and 1.7V to 3.6V IO tolerance also let it co-exist with 1.8V sensors. When designing with this MCU, place four 0.1 µF + 1 µF decoupling pairs near the VDDIO/VDDCORE pin groups, route the 12 MHz crystal traces symmetrically, and use a 4-layer backup across IC pin groups to keep the high-speed USB and Ethernet impedance at 90 Ω differential. Provide a 32.768 kHz low-power crystal on the XIN32/XOUT32 pads if RTC wake-from-backup is required.
