ATSAM4S8BB-AN - 120MHz Cortex-M4 MCU | Microchip
MPN： ATSAM4S8BB-AN ✓ 啟用中ATSAM4S8BB-AN 概覽
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripherals, and interface logic into one device. In the product hierarchy, this part is an ARM Cortex-M4 MCU, a 32-bit RISC microcontroller, a semiconductor, and a programmable embedded-control component. Its combination of Flash program memory, SRAM working memory, and high operating frequency supports both control tasks and data-intensive embedded applications without a separate external memory interface.
The verified product information identifies a maximum clock frequency of 120 MHz, 512 KB Flash, 128 KB SRAM, a 1.62 V to 3.6 V operating supply, and 200 uA/MHz power consumption. The ATSAM4S8BB-AN is packaged in a green, extended-temperature 64-LQFP. Its 32-bit architecture provides substantially more arithmetic and addressing capability than an 8-bit MCU, while the integrated 512 KB Flash supports larger embedded programs and 128 KB SRAM provides working space for protocol handling, buffers, and control logic.
Typical applications include USB-connected embedded controllers, industrial equipment, communication modules, data acquisition systems, and compact control platforms. The 120 MHz operating speed allows the Cortex-M4 core to process multiple interrupts, peripheral transfers, and control loops efficiently. The device is suitable when firmware requires more memory and processing capability than a basic 8-bit or low-cost 16-bit microcontroller, provided the board design follows the electrical and pin requirements specified by the manufacturer.
The primary design consideration is supply integrity. The operating range begins at 1.62 V and extends to 3.6 V, so the power rail, decoupling capacitors, reset circuitry, clock configuration, and I/O voltage limits must be checked against the manufacturer documentation. Because exact peripheral, pin, and electrical details are not supplied in the verified excerpts, do not infer those values from the family description.
This product data combines the verified Microchip family specifications with distributor sourcing information and distinguishes verified facts from fields requiring datasheet confirmation. It is intended for engineers evaluating the ATSAM4S8BB-AN for embedded industrial, communication, and USB-related designs.

典型應用
ATSAM4S8BB-AN 適用於 6 應用s: Industrial Embedded Control, USB Communication Module, Data Acquisition System, Communication Gateway, Motor and Automation Controller, Compact Control Board.
Industrial Embedded Control
ATSAM4S8BB-AN fits industrial embedded controllers that require a 120 MHz ARM Cortex-M4 core, 512 KB of Flash, and 128 KB of SRAM in a compact 64-LQFP package. The processor speed supports responsive control loops, interrupt handling, and communication tasks, while the integrated memory reduces the need for external storage. Its 1.62 V to 3.6 V operating range fits low-voltage embedded rails when the board supply and I/O levels are designed accordingly. The verified data does not identify the exact peripheral mix, so timer, ADC, communication, and isolation requirements must be checked against the exact datasheet.
推薦
USB Communication Module
The ATSAM4S8BB-AN can be evaluated for USB communication equipment because its Cortex-M4 core operates up to 120 MHz and includes 512 KB of Flash and 128 KB of SRAM for protocol stacks, buffers, and application firmware. The memory headroom is useful when USB device or host firmware must coexist with configuration storage and control logic. Before selecting it, verify the exact ATSAM4S8BB-AN USB peripheral availability, data pins, transceiver interface, clock requirements, and 1.62 V to 3.6 V electrical limits in the manufacturer documentation. USB compliance also depends on the board layout and connector implementation.
推薦
Data Acquisition System
ATSAM4S8BB-AN is suitable for a compact data-acquisition controller when the application needs a 32-bit processor and substantially more memory than a basic MCU. The verified 512 KB Flash provides room for acquisition firmware, calibration tables, and communication routines, while 128 KB SRAM can support sample buffers and working state. The reported 12-bit ADC resolution is also a relevant signal-chain identifier for sensor interfaces, although the exact number and mapping of ADC channels are not supplied here. Confirm the ADC input range, sampling behavior, trigger sources, pin multiplexing, and analog grounding before designing the front end.
推薦
Communication Gateway
The ATSAM4S8BB-AN can serve as the central processor in a communication gateway because the 120 MHz Cortex-M4 core can handle protocol processing while 512 KB of Flash and 128 KB of SRAM accommodate firmware and packet buffers. Its 64-LQFP package provides a practical surface-mount form factor for compact gateway boards. The device should be selected only after confirming whether the required serial interfaces, Ethernet or USB support, pin multiplexing, and electrical levels are present on the exact package. A gateway design should also budget regulator headroom, decoupling, clock stability, and protection for external communication lines.
推薦
Motor and Automation Controller
ATSAM4S8BB-AN is a candidate for compact automation and motor-control supervisory systems because its 120 MHz core can execute multiple control and communication tasks while the 128 KB SRAM supports state machines and command buffers. The 1.62 V to 3.6 V supply range permits integration with low-voltage digital systems, but motor circuitry generally requires separate drivers, protection, and isolation. Verify the exact timer channels, PWM outputs, capture inputs, ADC resources, and pin assignments before assigning control functions. Keep high-current switching paths away from sensitive analog and communication areas, and validate thermal performance across the required -40 C to +105 C operating range.
推薦
Compact Control Board
ATSAM4S8BB-AN is appropriate for compact embedded control boards where 512 KB of Flash and 128 KB of SRAM must coexist with a small 64-LQFP footprint. The 120 MHz core provides performance margin for control algorithms, logging, and communications, while the 1.62 V to 3.6 V operating range supports low-voltage system design. The MCU should be paired with local bypass capacitors, a controlled clock and reset implementation, and careful separation between digital and analog sections. Because the supplied data does not expose the complete pinout or all peripheral options, use the exact package drawing during PCB layout and confirm unused-pin requirements before fabrication.

主要差異化特點

- Large integrated memory for embedded firmware (對比ATSAM4S8BB-ANR)
- Low-voltage operation (對比ATSAM4S8BA)
設計說明
Design the ATSAM4S8BB-AN supply within the verified 1.62 V to 3.6 V operating range. Place local bypass capacitors close to the MCU supply pins, verify the regulator’s transient response, and ensure the selected external components remain valid across the required -40 C to +105 C temperature range. The listed 200 uA/MHz is a family-level power-consumption figure, not a complete board power budget; estimate total current by including the core, peripherals, I/O loads, and external circuitry.
Use the exact ATSAM4S8BB-AN package drawing for footprint, pin numbering, and exposed thermal or ground information. Keep the 64-LQFP layout compact but route high-current and sensitive analog nets away from processor and communication signals. Confirm the manufacturer’s recommended decoupling and clock layout before fabrication because the supplied search excerpts identify the package but do not provide the complete pinout or layout recommendations.
Treat clock, reset, and communication interfaces as layout-sensitive nets. Provide a stable clock source, clean reset behavior, and short return paths, then validate edge rates and peripheral timing with an oscilloscope during prototype bring-up. The 120 MHz core rating does not guarantee signal integrity by itself; board parasitics, supply impedance, load capacitance, and external transceiver behavior determine whether a communication interface operates reliably.
合規資訊
The verified distributor listing describes a green, extended-temperature, 64-LQFP device, but the supplied excerpts do not explicitly provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Confirm formal compliance with Microchip’s current product documentation.
