ATSAM4E8CB-AN - 120MHz Cortex-M4 512KB MCU | Microchip
MPN: ATSAM4E8CB-AN ✓ AktifATSAM4E8CB-AN Ringkasan
An ARM Cortex-M4 microcontroller is a low-power embedded-processing component that executes firmware from internal flash while using SRAM for working data and stack operations. The Cortex-M4 architecture belongs to the broader ARM processor family and provides a conventional pipeline, exception handling, and integrated DSP instructions. This SAM4E device is a microcontroller IC rather than a general-purpose processor because it integrates memory and embedded peripherals within one compact package.
Verified product information identifies a maximum clock frequency of 120 MHz, 512 KB of flash organized as 512K x 8 bits, and 128 KB of SRAM. The processor-based design includes a floating-point unit and a high-data-bandwidth architecture. The green package, extended-temperature ordering designation, and revision B marking provide useful procurement and lifecycle information for industrial embedded-product planning.
The 100-LQFP package provides a substantial pin count for embedded interfaces and board-level routing while remaining compatible with mainstream leaded-package assembly processes. Compared with a smaller microcontroller package, the ATSAM4E8C family offers more connection options for mixed-signal, communications, control, and data-acquisition products. The 14 x 14 mm footprint is nevertheless larger than compact QFN and DFN alternatives.
Typical uses include industrial automation controllers, connected industrial equipment, medical monitoring instruments, building and access-control systems, and embedded communications gateways. Its 120 MHz Cortex-M4 core and 512 KB flash provide margin for protocol stacks, control loops, data logging, and supervisory firmware, while the floating-point unit supports calculations involving fractional or floating-point values.
Designers should verify the complete pinout, peripheral configuration, clock plan, and operating limits against the manufacturer datasheet before layout release. The verified data confirms the MCU identity, processor, memory, frequency, and package, but it does not provide the detailed pin names, individual peripheral ratings, or complete electrical operating limits needed for a production schematic.
This page combines verified distributor availability, exact published pricing, package information, lifecycle guidance, family alternatives, and practical selection guidance. It also distinguishes documented characteristics from parameters that still require confirmation from the ATSAM4E8C datasheet and errata, providing a more engineering-focused basis for sourcing and design review.

Medical Monitoring Instruments
The ATSAM4E8CB-AN is a candidate for embedded medical monitoring equipment where a control system must combine deterministic control with communications and data logging. The 120 MHz Cortex-M4 core can execute acquisition control, signal-processing, and user-interface tasks, while 512 KB of flash accommodates firmware and nonvolatile parameters and 128 KB of SRAM supports buffered samples. Its floating-point unit may benefit scaling and filtering algorithms. Because the supplied data does not identify medical-specific certification or safety classification, the device should not be assumed suitable for a regulated clinical role without a documented risk assessment, electrical verification, and compliance review.

Building Access Control Systems
The ATSAM4E8CB-AN can serve in access-control and security equipment requiring persistent network handling, local credential logic, and multiple peripheral connections. Its 512 KB flash provides room for application firmware and configuration, while the 120 MHz Cortex-M4 core can manage protocol processing and real-time actuator decisions. The 100-pin LQFP offers more board-level interface options than a small microcontroller package and may simplify connections to readers, lock-control circuitry, status indicators, and communications transceivers. The verified data does not list the complete peripheral set, so final suitability depends on confirming required interfaces, voltage levels, timing, and security requirements from the manufacturer datasheet.

Industrial Communication Gateways
The ATSAM4E8CB-AN is suitable for protocol-conversion and industrial gateway concepts built around the SAM4E platform. Its 120 MHz Cortex-M4 processing capability supports simultaneous handling of serial traffic, routing logic, diagnostics, and local configuration, while 512 KB of flash and 128 KB of SRAM provide storage for firmware and packet buffers. The floating-point unit and high-data-bandwidth architecture can assist throughput-oriented control tasks. Engineers should verify the exact communication peripherals, DMA behavior, Ethernet or serial interfaces, and electrical characteristics before assigning network traffic, since those details are not exposed in the supplied verified snippets.

Data Acquisition and Control
The ATSAM4E8CB-AN can anchor a data-acquisition and control subsystem that needs more local memory and processing than a basic 8-bit controller. The 120 MHz Cortex-M4 core supports timing, scaling, filtering, and supervisory logic, while 512 KB of flash stores firmware and 128 KB of SRAM can hold acquisition buffers or intermediate results. The 100-pin LQFP provides a practical route to multiple sensors, converters, and digital interfaces. Exact analog-front-end integration, converter resolution, sampling timing, and peripheral assignments are not specified in the verified data and must be checked against the ATSAM4E8C datasheet and pin table.

Catatan Desain
Do not release a PCB or firmware solely from the ATSAM4E8CB-AN family name and distributor headline specifications. The verified data confirms the 100-LQFP package, 120 MHz Cortex-M4 core, 512 KB flash, and 128 KB SRAM, but it does not expose individual pin assignments, alternate-function multiplexing, or exposed-pad requirements. Download the current Microchip ATSAM4E8C datasheet and errata, then check every power, ground, reset, clock, debug, and peripheral connection against the selected ordering code.
Budget the ATSAM4E8CB-AN only after obtaining its verified supply-voltage range and mode-dependent current specifications. The supplied web data contains no operating voltage, active current, or sleep-current values, so a numerical power calculation would be speculative. For a functioning design, include the core and I/O current, regulator efficiency, startup behavior, and peripheral loading in the system power budget, and provide local bypass capacitance exactly as directed by the manufacturer reference design.
Use the verified 14 x 14 mm 100-LQFP footprint and follow the current Microchip land pattern, solder-mask, paste, and thermal-pad details rather than generating dimensions from a generic LQFP library. Preserve the package orientation defined by pin 1 and the exposed thermal pad, if present. Because the supplied source does not include a complete pin table or package drawing, a CAD footprint should be cross-checked mechanically and electrically before fabrication.
Plan the 100-pin device around the complete ATSAM4E8C peripheral map rather than only the functions mentioned in the distributor summary. The verified material confirms a floating-point unit and high-data-bandwidth architecture but does not enumerate communication interfaces or DMA resources. Review pin-mux options and package alternatives in the official documentation, reserve pins for programming and debug, and route high-speed or sensitive interfaces away from potential switching nodes before final placement.
Informasi Konformitas
The verified data identifies a green package and extended-temperature ordering designation but does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. AEC-Q100 is not applicable to this general-purpose industrial microcontroller classification unless Microchip separately qualifies a specific ordering code.
