ATSAM4LS4CA-CFUR 개요
A microcontroller unit (MCU) is a single integrated circuit that combines a processor core, memory, and programmable peripherals into one chip, sitting at the device level of the embedded-systems hierarchy (MCU -> embedded processor -> semiconductor IC). The SAM4L family is based on the high-performance 32-bit ARM Cortex-M4 RISC processor, providing DSP-oriented instructions and efficient interrupt handling for low-power embedded designs.
Key features of the ATSAM4LS4CA-CFUR include the ARM Cortex-M4 core at 48 MHz for computationally capable but energy-conscious applications, 256KB (256K x 8) of on-chip Flash for code storage, and a 100-VFBGA (7x7 mm) ball grid array footprint that saves board area in space-constrained products. The part is specified for industrial temperature range operation and is available as a Green (RoHS-oriented) package with MSL rating A per distributor listings.
From a technical perspective, the SAM4L series emphasizes low active and sleep-mode power consumption while retaining the Cortex-M4 integer DSP capability, making it distinct from Cortex-M3-based parts at similar clock speeds. The 100-ball VFBGA requires precise PCB land-pattern design and reflow assembly, but yields the smallest possible footprint for a 100-pin SAM4L device.
Typical applications include portable and battery-powered instruments, industrial sensing nodes, consumer appliances, and low-power IoT end points where a 48 MHz Cortex-M4 with 256KB Flash provides adequate performance headroom.
When designing with this device, plan power-delivery decoupling for the BGA ballout and verify Flash capacity against application growth, since the 256KB density sits mid-range in the SAM4L family.

일반적인 애플리케이션
ATSAM4LS4CA-CFUR 적합 용도: 6 애플리케이션s: Portable Battery-Powered Instruments, Industrial Sensing Nodes, Low-Power IoT End Points, Consumer Appliance Control, Medical Monitoring Devices, Embedded System Prototyping.
Portable Battery-Powered Instruments
The ATSAM4LS4CA-CFUR fits portable instruments because its SAM4L architecture targets low active and sleep-mode power while the 48 MHz ARM Cortex-M4 core provides enough throughput for measurement math and display updates. With 256KB of Flash, firmware including calibration routines and a UI layer fits without external memory. The 7x7 mm 100-VFBGA package lets designers place the MCU under or beside the battery on a compact PCB. The trade-off is assembly cost: the BGA requires reflow capability, but saves significant board area versus a 100-lead LQFP in handheld enclosures.
추천
Industrial Sensing Nodes
In industrial sensing nodes, the ATSAM4LS4CA-CFUR is a strong fit because the industrial temperature grade supports factory-floor environments and the Cortex-M4 core executes digital filtering and FFT-based vibration analysis at 48 MHz without a co-processor. The 256KB Flash holds communication stacks plus sensing firmware, and the SAM4L peripheral set interfaces with ADCs and transceivers over standard serial buses. The Green MSL A VFBGA package withstands standard industrial reflow profiles. Designers should budget decoupling on all VDD balls and confirm sleep current against the datasheet for battery-backed nodes.
추천
Low-Power IoT End Points
For battery-powered IoT end points, the ATSAM4LS4CA-CFUR offers the combination that matters most: a 48 MHz Cortex-M4 with DSP instructions for protocol and crypto processing, 256KB Flash for a full wireless stack, and the SAM4L family's low-power design intent. The 100-VFBGA (7x7 mm) footprint keeps the radio module and power section room on small PCBs. Firmware should exploit sleep modes between sensor polls; the savings achievable depend on the datasheet sleep-mode currents for the selected power domain configuration, so size the battery from measured profiles rather than estimates.
추천
Consumer Appliance Control
Consumer appliance control boards benefit from the ATSAM4LS4CA-CFUR's balance of performance and integration: the 48 MHz Cortex-M4 handles motor-control loops, touch or button scanning, and display drivers concurrently, while 256KB Flash stores UI assets and safety routines. The industrial temperature grade comfortably exceeds household ambient requirements, improving long-term reliability margins. The 100-ball VFBGA reduces controller PCB area, which matters in dense appliance mainboards. Manufacturers choose the R (tape-and-reel) suffix version for high-volume pick-and-place assembly lines.
추천
Medical Monitoring Devices
Battery-powered medical monitors require both processing headroom and low power, which the ATSAM4LS4CA-CFUR addresses: the Cortex-M4 DSP instructions accelerate physiological signal filtering (ECG/SpO2 pipelines), and the SAM4L low-power design extends battery life between charges. The 256KB Flash accommodates signal-processing firmware, calibration data, and a BLE or wired telemetry stack. The compact 100-VFBGA package supports small wearable or bedside form factors. Medical designers must validate the part against their quality system and confirm compliance documentation directly with Microchip for regulated deployments.
추천
Embedded System Prototyping
The ATSAM4LS4CA-CFUR serves as a production target for SAM4L-based designs prototyped on evaluation hardware. Because all 100-VFBGA SAM4L variants share one ballout, a single PCB footprint accepts the 256KB LS4 used during development or the LC8/LS8 variants when firmware outgrows 256KB - eliminating respins for memory upgrades. Teams that need visual inspection and hand rework during bring-up can prototype on the pin-equivalent-in-function leaded ATSAM4LS4CA-AU and migrate to the VFBGA for production, since software and peripherals are identical across packages.

설계 노트
The 100-VFBGA (7x7 mm, 0.8 mm-class ball pitch) requires a carefully controlled land pattern and via-in-pad or dogbone fanout. Follow the SAM4L datasheet and Microchip BGA land-pattern guidelines: define non-solder-mask-defined (NSMD) pads and route power balls to a dedicated plane. Verify the exact ball pitch against the mechanical drawing in the manufacturer datasheet before generating your footprint - do not scale from an LQFP footprint.
Place 100 nF ceramic decoupling capacitors at each VDD ball pair with a bulk capacitor (10 uF class) near the supply entry. The SAM4L integrates multiple power domains (VDDCORE/VDDIO per datasheet); read the SAM4L datasheet power-supply section to confirm the domain arrangement and sequencing requirements for the ATSAM4LS4CA-CFUR before finalizing the power tree. Estimated: budget at minimum one decoupling cap per two supply balls given the 100-ball array.
Three frequent mistakes with this MPN: (1) ordering the non-R (tray) suffix for a reel-fed SMT line or vice versa - the R suffix means tape and reel; (2) assuming a cross-brand Cortex-M4 MCU is a drop-in - only same-family 100-VFBGA SAM4L variants share this ballout; (3) sizing firmware against 256KB Flash without reserve - choose ATSAM4LC8CA-CFUR (512KB, same footprint) if OTA updates or feature growth are planned.
규정 준수 정보
