ATSAM4E16CA-AN 개요

The Microchip Technology ATSAM4E16CA-AN is a 32-bit ARM Cortex-M4 microcontroller with a floating point unit, running at up to 120 MHz, with 1 MB of embedded Flash and 128 KB of SRAM, housed in a 100-pin LQFP (14x14 mm) package.

A microcontroller (MCU) is a single-chip computer that integrates a processor core, memory, and peripherals on one die, forming the lowest level of the embedded-system hierarchy: MCU -> embedded processor -> system-on-chip -> computing platform. The SAM4E series belongs to Microchip's SMART ARM-based Flash MCU family, positioned for connected industrial and smart-energy applications that need both DSP-class math performance and Ethernet connectivity in a single chip.

Key features of the ATSAM4E16CA-AN include the ARM Cortex-M4 core with 2 KB instruction cache, a hardware Floating Point Unit (FPU) and DSP instructions, a Memory Protection Unit (MPU), Thumb-2 instruction set support, and a supply range of 1.62 V to 3.6 V. The SAM4E series integrates an Ethernet MAC, making it distinct from the otherwise similar SAM4C series, which targets smart energy metering without Ethernet.

Architecturally, the Cortex-M4 achieves high data bandwidth through its Harvard bus structure and the 2 KB cache, while the FPU executes single-precision floating-point math in hardware - valuable for control loops, protocol stacks, and measurement algorithms that would otherwise burden the CPU with software emulation.

Typical applications include industrial control and automation nodes, smart energy metering gateways, building control, and networked sensors that use the on-chip Ethernet MAC for fieldbus or IoT backhaul.

When designing with this device, plan for decoupling of the multiple supply domains (1.2 V core domain is internally regulated; 2.5 V/3.3 V I/O and analog domains per the datasheet) and verify the 100-LQFP (14x14) footprint, because suffix variants differ in packing rather than footprint.

일반적인 애플리케이션

ATSAM4E16CA-AN 적합 용도: 6 애플리케이션s: Industrial Control and Automation, Smart Energy Metering, Networked IoT Sensor Gateways, Building Automation Controllers, Medical and Diagnostic Instruments, Embedded Networking and Communication Equipment.

🏭

Industrial Control and Automation

The ATSAM4E16CA-AN fits industrial control nodes where a 120 MHz Cortex-M4 with hardware FPU executes PID and motion-control loops deterministically while the 1 MB Flash holds protocol stacks and a bootloader with headroom for field firmware updates. Its SAM4E-series Ethernet MAC allows the controller to serve web interfaces or connect to plant SCADA networks without an external network processor. The MPU supports functional partitioning of safety-relevant code, and Thumb-2/DSP instructions accelerate filtering of ADC-sampled sensor data. Designers typically pair it with external PHY and isolated I/O to build compact single-chip control heads for conveyors, pumps, and process skids.

⚡

Smart Energy Metering

Microchip positions the SAM4E/SAM4C families explicitly for smart energy metering. The ATSAM4E16CA-AN's DSP instructions and single-precision FPU compute RMS, FFT-based harmonic analysis, and energy accumulation from ADC samples at line frequency without host support, while 1 MB Flash accommodates DLMS/COSEM or other metering firmware plus secure bootloaders. The 1.62 V to 3.6 V supply range supports battery-backed metering front ends, and the MPU helps isolate billing-critical code. Where metering designs do not need Ethernet, the pin-compatible ATSAM4C16CB-AU offers a metering-optimized peripheral set; the SAM4E suits data-concentrator and gateway meters that backhaul over Ethernet.

🧩

Networked IoT Sensor Gateways

For IoT gateways that aggregate field sensors and report over a wired uplink, the ATSAM4E16CA-AN provides a single-chip solution: the 120 MHz Cortex-M4 runs an RTOS with an lwIP TCP/IP stack on the integrated Ethernet MAC, 128 KB SRAM buffers packet traffic and sensor queues, and 1 MB Flash stores application plus OTA update images. The 2 KB cache and Harvard bus architecture sustain high data bandwidth for concurrent sensor sampling and network I/O. Engineers commonly connect the MCU to sensor hubs over TWI/SPI and use the FPU for on-edge analytics such as vibration FFTs, reducing cloud bandwidth and improving response latency in condition-monitoring deployments.

🏢

Building Automation Controllers

Building automation nodes benefit from the ATSAM4E16CA-AN's combination of network connectivity and real-time control. The integrated Ethernet MAC supports BACnet/IP or Modbus TCP implementations directly on-chip, while the 120 MHz FPU-equipped core handles HVAC control algorithms, scheduling, and trending logs in the 128 KB SRAM. The 1 MB Flash stores multiple protocol personalities for product-line variants on one PCB. The wide 1.62 V to 3.6 V operating range tolerates supply sag from shared building power rails, and the 100-LQFP (14x14) two-row peripheral footprint simplifies routing of the many I/O needed for damper, valve, and sensor interfaces in wall-mounted and panel controllers.

💊

Medical and Diagnostic Instruments

Benchtop and portable diagnostic instruments use the ATSAM4E16CA-AN for its DSP-accelerated signal processing: the hardware FPU and DSP instructions run digital filtering, peak detection, and calibration math on sensor waveforms at 120 MHz, while the MPU enforces memory partitioning useful in instrument software architectures. The 1 MB Flash retains device configuration, patient-calibration tables, and UI assets, and the Ethernet MAC streams data to lab information systems without an additional processor. The low-noise on-chip ADC channels and precise TWI/SPI timing support front ends such as optical and pressure sensors, and the 100-LQFP 14x14 package suits compact handheld instrument housings.

🌐

Embedded Networking and Communication Equipment

Communication equipment such as industrial routers, serial-device servers, and protocol converters leverage the SAM4E's defining Ethernet MAC plus multiple USARTs to bridge legacy serial devices onto IP networks. The 120 MHz Cortex-M4 with 2 KB cache sustains line-rate bridging for 10/100 Ethernet traffic with protocol translation in the 128 KB SRAM, and 1 MB Flash holds stacks for Modbus, PROFINET-style fieldbus gateways, or custom tunneling. Hardware FPU offloads encryption-adjacent math and traffic statistics. Because the device is Flash-based with in-application programming support, firmware updates can be delivered remotely over the network - critical for deployed communication infrastructure in inaccessible locations.

Always request a live quote for volume orders.
Where to buy ATSAM4E16CA-AN online?
You can buy the ATSAM4E16CA-AN from XAIPART as well as major distributors: DigiKey (product page 4557084), Mouser, and Octopart-listed channels. Octopart reports 12 distributors carrying the part and Heisener lists in stock as of the 2026-09-20 data pull. For production volumes, request quotes from multiple distributors since lead times are listed as 'to be confirmed' on some channels.
Is ATSAM4E16CA-AN in stock and what is the lead time?
Yes - distributor data as of 2026-09-20 shows stock availability: Heisener lists in stock, and DigiKey states 'Buy now, ships today' for the ATSAM4E16CA-AN. However, some channels list the lead time as 'to be confirmed,' so for large production quantities you should request a formal lead-time confirmation before scheduling builds.
What is the difference between ATSAM4E16CA-AN and ATSAM4C16CB-AU?
Both are 120 MHz ARM Cortex-M4 MCUs with 1 MB Flash in 100-pin LQFP packages, but the ATSAM4E16CA-AN belongs to the SAM4E series, which integrates an Ethernet MAC, while the ATSAM4C16CB-AU belongs to the SAM4C series aimed at smart energy metering. According to the Utmel comparison of the two parts, the SAM4C variant targets metering applications; if your design needs Ethernet, choose the SAM4E.
What is the best drop-in replacement for ATSAM4E16CA-AN?
The closest drop-in replacement is the ATSAM4SD32CA, a same-family Microchip/Atmel Cortex-M4 MCU in the same 100-LQFP (14x14) pin-compatible footprint, offering 2 MB of dual-bank Flash for designs needing more code space. Within the SAM4E family, the ATSAM4E8CA offers the same pinout with 256 KB Flash for cost-reduced builds. Always verify peripheral counts and pin multiplexing against the SAM4E/SAM4SD datasheet before layout reuse.
Is ATSAM4E16CA-AN suitable for industrial Ethernet applications?
Yes. The ATSAM4E16CA-AN belongs to the SAM4E series, whose defining series feature versus the related SAM4C is an integrated Ethernet MAC, running alongside the 120 MHz Cortex-M4 with hardware FPU. This makes the part well suited for industrial nodes that need a 10/100 Ethernet uplink, deterministic control loops, and single-chip integration, provided you add an external PHY such as a KSZ8081 to complete the physical layer.
When should I choose ATSAM4E16CA-AN over ATSAM4C16CB-AU?
Choose the ATSAM4E16CA-AN when your application requires Ethernet connectivity, because the SAM4E series includes an Ethernet MAC that the SAM4C series does not provide. Choose the ATSAM4C16CB-AU for smart energy metering designs that prioritize metering-specific peripherals and do not need a network uplink. Both share the 120 MHz Cortex-M4 core with FPU, 1 MB Flash, and 100-pin LQFP packaging, so migration is straightforward if requirements change.
What is the best Microchip equivalent for ATSAM4E16CA-AN in a shortage?
The best same-brand equivalents come from within the SAM4E and SAM4SD families: the ATSAM4SD32CA (same 100-LQFP footprint, 2 MB dual-bank Flash) for code-space headroom, and the ATSAM4E8CA (same pinout, 256 KB Flash) for cost reduction. No cross-brand pin-compatible equivalent for this 100-LQFP ARM MCU was found in the verified cross-reference data, so Microchip same-family parts are the recommended substitution path.
Where to download the ATSAM4E16CA-AN datasheet PDF?
You can download the ATSAM4E16CA-AN datasheet PDF from Microchip's official product page at microchip.com/en-us/product/ATSAM4E16C, or via datasheet aggregators such as datasheets.com and Octopart, which host the latest revision. Microchip's product page notes that for new designs they highly recommend considering Revision B for prototypes and production, so always confirm you are using the current document revision.
Where can I find the ATSAM4E16CA-AN pinout for the 100-LQFP package?
The complete 100-pin LQFP (14x14 mm) pinout for the ATSAM4E16CA-AN is defined in the SAM4E series datasheet available from Microchip's product page. Because pin functions are heavily multiplexed (GPIO, Ethernet, USART, SPI, TWI, ADC channels), consult the peripheral multiplexing tables in the datasheet rather than copying a partial diagram. XAIPART does not reproduce the full 100-pin map on this page to guarantee accuracy.
Does the ATSAM4E16CA-AN have a floating point unit and DSP instructions?
Yes. According to the SAM4E series datasheet, the ATSAM4E16CA-AN's ARM Cortex-M4 core includes a hardware single-precision Floating Point Unit (FPU) and DSP instructions, plus a Memory Protection Unit (MPU) and Thumb-2 instruction support. The hardware FPU executes single-precision math without software emulation, which significantly accelerates control algorithms, filtering, and signal-processing code compared to Cortex-M3-class parts.
What supply voltage does the ATSAM4E16CA-AN require?
The ATSAM4E16CA-AN operates from a supply range of 1.62 V to 3.6 V, with internal 1.2 V, 2.5 V, and 3.3 V supply domains per distributor parametric data (datasheets.com lists '1.2V/2.5V/3.3V'). In practice, designs typically power it from a single 3.3 V rail; the core domain is handled on-chip. Use low-ESR decoupling on each supply pin group per the SAM4E datasheet power-supply recommendations.
What is the lifecycle status of ATSAM4E16CA-AN?
The ATSAM4E16CA-AN is active and in production: DigiKey and Mouser both list it as an orderable current product, and Microchip's product page for the ATSAM4E16C remains live as of 2026-09-20. Note Microchip's guidance on the product page that for new designs they highly recommend considering Revision B silicon for prototypes and production - existing designs can continue with current supply without restriction.
Is the ATSAM4E16CA-AN the same as the ATSAM4E16CA-AU?
Yes and no - the ATSAM4E16CA-AN and ATSAM4E16CA-AU share the identical die, 100-LQFP (14x14) package, pinout, and electrical specifications; the suffix difference reflects packing (tray versus tape-and-reel style ordering options) under Atmel/Microchip ordering conventions, not silicon differences. Electrically they are interchangeable; choose the suffix that matches your assembly line's handling method and confirm packing availability with your distributor.

선택 가이드

Choose the ATSAM4E16CA-AN when you need a 120 MHz Cortex-M4 with hardware FPU, 1 MB Flash, and an integrated Ethernet MAC in a single 100-LQFP chip - typical for industrial controllers, networked gateways, and data-concentrator meters. Choose the ATSAM4SD32CA-AU if your firmware needs more than 1 MB (2 MB dual-bank Flash, same pinout) or dual-image OTA updates. Choose the ATSAM4E8CA-AU for cost-reduced builds that fit in 256 KB Flash while keeping the identical footprint for future upgrades. Choose the ATSAM4C16CB-AU only for smart-energy applications that do not require Ethernet, since the SAM4C drops the MAC. All four share the 100-LQFP (14x14) footprint, enabling PCB reuse across the family; verify die revision B and peripheral multiplexing tables before finalizing layouts.

설계 노트

Power the ATSAM4E16CA-AN from a clean 3.3 V rail within the 1.62 V to 3.6 V datasheet range; the 1.2 V core domain is regulated on-chip, so do not inject external voltage onto VDDCORE pins. Distributor parametric data lists 1.2 V/2.5 V/3.3 V domains - follow the SAM4E datasheet pin-by-pin supply table for VDDIO, VDDCORE, VDDPLL, and VDDA groupings, each with its own 100 nF plus bulk decoupling. Place a 10 uF bulk capacitor near each supply group entry point on the PCB.

For the 100-LQFP (14x14 mm) footprint, escape the 0.5 mm pitch leads with 0.25 mm traces and place decoupling capacitors on the opposite side of the board directly under the package. The Ethernet MAC signals (RMII/MII to the external PHY) should be length-matched within a few centimeters and kept away from the 12/48 MHz crystal traces. Use a solid ground plane and connect the PHY magnetics per the PHY vendor reference design (e.g., KSZ8081 evaluation schematics) to pass EMC testing.

Microchip explicitly notes on the product page that for new designs they 'highly recommend to consider Revision B for prototypes and production' - check the die revision marking when receiving stock and when qualifying alternates such as the ATSAM4SD32CA or ATSAM4E8CA, whose peripheral multiplexing tables differ subtly. Also verify suffix meaning: -AN (this part, tray) vs -AU differ in packing, not silicon; ordering the wrong suffix can strand a reel-fed assembly line.
