ATSAM4E16CA-AN - 120MHz Cortex-M4, 1MB Flash MCU | Microchip

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.

ATSAM4E8EA-AN - 120MHz Cortex-M4 512KB Flash MCU | Microchip

The Microchip Technology ATSAM4E8EA-AN is a 32-bit ARM Cortex-M4 SAM4E-series microcontroller operating at up to 120 MHz, with 512 KB of embedded flash memory, in a 144-lead LQFP package measuring 20 mm by 20 mm. The part is identified by DigiKey as an ARM Cortex-M4 MCU with a 512K by 8 flash organization and is positioned for embedded applications requiring real-time control, high-speed data handling, and extensive peripheral integration. A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals on one integrated circuit. The Cortex-M4 core belongs to the ARM processor family and uses a reduced instruction set architecture tailored for embedded control. Within the product hierarchy, ATSAM4E8EA-AN is an ARM-based MCU, a microcontroller, and an integrated circuit. Its 120 MHz operating frequency allows software to execute control loops, communication protocols, and data-processing tasks while dedicated peripherals handle time-sensitive interface functions. The verified product listing identifies four headline characteristics: a 32-bit ARM Cortex-M4 processor, a maximum clock speed of 120 MHz, 512 KB of flash memory, and a 144-LQFP 20 mm by 20 mm package. These figures make the device suitable for industrial controllers, embedded automation equipment, communication modules, human-interface systems, and connected products where substantial program storage and a moderate pin count are required. The large leaded package also supports designs using fine-pitch PCB routing and provides a larger thermal and pin-termination surface than compact leadless packages. The SAM4E family combines a high-performance processor core with embedded memories and communication peripherals. At 120 MHz, the processor provides substantially more instruction throughput than many lower-clock 8-bit or 32-bit microcontrollers. The 512 KB flash permits larger firmware, bootloaders, protocol stacks, and application logic to coexist, while SRAM and external-interface details remain unavailable in the supplied verified data. Review the complete manufacturer documentation before assigning memory sizes, peripheral channels, clock configurations, or interrupt resources to the design. Typical deployments include industrial machine controls, motor-control adjuncts, building automation controllers, data acquisition units, networking equipment, and embedded gateways. In each case, the 120 MHz Cortex-M4 core can execute application logic while the MCU architecture supports deterministic peripheral operation. The 144-LQFP package is particularly suitable for prototypes and industrial boards where through-hole assembly, inspection, or rework is preferred over very fine-pitch BGA handling. The primary design consideration is that component identity alone does not establish board-level compatibility. Engineers must verify power architecture, clocking, pin multiplexing, peripheral availability, package dimensions, programming interfaces, and memory requirements against the manufacturer datasheet. The available web evidence also identifies a newer revision recommendation for new designs, so ATSAM4E8EA-AN should be checked for revision and lifecycle status before production release. This page consolidates verified distributor specifications, current commercial availability, package information, and engineering selection guidance. It also separates confirmed facts from unavailable technical details, allowing procurement and design teams to identify the remaining datasheet checks without mistaking inferred or unreported parameters for guaranteed specifications.
