ATSAM4S8BA-UUR - 120MHz Cortex-M4 MCU | Microchip
MPN: ATSAM4S8BA-UUR ✓ सक्रियATSAM4S8BA-UUR अवलोकन
A microcontroller is an integrated circuit that combines a processor core, program memory, data memory, and peripherals within one package. The ARM Cortex-M4 core provides deterministic 32-bit instruction execution, while the SAM4S8 family integrates the processor with embedded serial controllers and other system resources. In the device hierarchy, the ATSAM4S8BA-UUR belongs to the SAM4S microcontroller family and the broader category of microcontrollers and embedded processors.
Principal features include a 120 MHz maximum operating speed, 512 KB of flash, 128 KB of SRAM, and a 1.62 V to 3.6 V supply range. The green 64-ball WLCSP construction supports space-constrained designs requiring a small component footprint. The manufacturer identifies the industrial-temperature, tape-and-reel configuration for production assembly and automated component placement.
The 120 MHz Cortex-M4 architecture is suitable for control loops, protocol handling, data acquisition, and supervisory functions that require more performance than a basic 8-bit controller. The 128 KB SRAM provides working space for protocol stacks, buffers, and application state, while the 512 KB flash stores firmware and configuration data. At the same time, the device remains a microcontroller rather than a general-purpose application processor, making it appropriate for embedded systems with defined peripheral and real-time requirements.
Typical uses include industrial interface modules, building automation controllers, communications equipment, data-acquisition systems, and compact consumer appliances. Its small WLCSP package is particularly useful when the PCB area is restricted, while the industrial-temperature designation supports designs intended for extended commercial environments.
Designers should confirm the complete pin configuration, exposed-ball requirements, decoupling, clock, programming, and reset recommendations in the manufacturer datasheet before layout release. PCB routing should also account for the fine-pitch 64-ball geometry and the manufacturer’s land-pattern requirements.
This page combines the manufacturer family specifications with package details, application guidance, comparison parameters, and practical design notes. It provides engineering context for component selection, footprint planning, firmware sizing, power budgeting, and supply-chain qualification.

सामान्य अनुप्रयोग
ATSAM4S8BA-UUR के लिए उपयुक्त है 6 अनुप्रयोगs: Industrial Communications Gateway, Data Acquisition and Sensor Hub, Building Automation Controller, Embedded Control and Automation Module, Battery-Powered Sensor Node, Audio Control and Interface Module.
Industrial Communications Gateway
The ATSAM4S8BA-UUR suits compact communications gateways that must process protocol traffic and supervisory logic within a restricted board area. Its 120 MHz ARM Cortex-M4 core provides deterministic 32-bit execution, while 128 KB of SRAM supports protocol state, packet buffers, and application variables. The 512 KB flash accommodates networking firmware, configuration records, and diagnostics. Because the 64-UFBGA WLCSP package uses fine-pitch balls, the design should follow the manufacturer land pattern and provide dense, low-impedance routing for power, clock, and high-speed signals.
अनुशंसित
Data Acquisition and Sensor Hub
The ATSAM4S8BA-UUR is appropriate for a compact sensor hub that gathers measurements, performs filtering, and forwards results over a digital interface. The 120 MHz Cortex-M4 core can execute sampling schedules and digital filtering, while 128 KB of SRAM accommodates sample buffers and working state. Its 1.62 V to 3.6 V supply range supports low-voltage sensor architectures and 3.3 V system rails. The small 64-UFBGA WLCSP footprint helps reduce board area, although careful decoupling and short analog-signal routing remain essential for accurate measurements.
अनुशंसित
Building Automation Controller
The ATSAM4S8BA-UUR fits building-automation controllers that coordinate sensors, actuators, and network interfaces on a space-limited board. Its 120 MHz Cortex-M4 performance supports multitasking control logic, and 128 KB of SRAM provides useful capacity for protocol stacks and status tables. The industrial -40C to +105C temperature designation supports equipment operating across extended ambient conditions. For a 64-UFBGA implementation, verify the recommended land pattern, maintain controlled supply decoupling, and isolate switching nodes from sensitive measurement paths.
अनुशंसित
Embedded Control and Automation Module
The ATSAM4S8BA-UUR can serve as the primary controller in a compact motion, process, or machine-interface module. Its 120 MHz Cortex-M4 core provides predictable execution for control algorithms and state-machine logic, while the 512 KB flash supports application firmware and calibration tables. The 128 KB SRAM reduces the need for external memory in moderate workloads. The 64-UFBGA package minimizes PCB consumption, but its fine-pitch assembly requires compatible placement equipment, adequate solder-paste control, and inspection provisions appropriate for the assembly process.
अनुशंसित
Battery-Powered Sensor Node
The ATSAM4S8BA-UUR can support a compact battery-powered sensor node when its operating modes and external load are carefully managed. The manufacturer lists power consumption of 200 uA/MHz, allowing designers to evaluate processing-related energy use against the 120 MHz performance capability. The 1.62 V minimum operating voltage also supports low-voltage power architectures. Deep-sleep behavior, wake sources, and peripheral leakage must be evaluated from the datasheet, and the 64-UFBGA footprint helps conserve board area in wearable or remote-monitoring products.
अनुशंसित
Audio Control and Interface Module
The ATSAM4S8BA-UUR is suitable for a compact audio-control module that handles configuration, monitoring, and communication rather than primary signal conversion. Its 120 MHz Cortex-M4 core can manage control protocols, status reporting, and system supervision, while 128 KB of SRAM supports interface buffering and state management. The 512 KB flash is sufficient for embedded control firmware and parameter storage. For audio-adjacent designs, keep switching regulators and noisy digital return paths separated from analog reference nodes, and use the manufacturer’s layout guidance for the 64-UFBGA package.

डिज़ाइन नोट्स
Use the manufacturer’s land pattern for the 64-UFBGA WLCSP rather than adapting a generic ball-grid footprint. The 64-ball geometry is fine pitch and leaves little routing margin between pads, so verify paste volume, reflow profile, pad-to-mask design, and assembly-line capabilities before release. Place input and bulk supply-decoupling capacitors close to their corresponding device pins, and keep the escape traces short to reduce supply inductance.
Design the 1.62 V to 3.6 V supply network around both average and peak processing demand. Estimated: at 120 MHz, the manufacturer’s 200 uA/MHz figure implies approximately 24 mA of processing-related current if applied directly; actual total current can differ because of peripherals, I/O loading, and operating mode. Validate this estimate against measured current before sizing the regulator, and confirm the voltage tolerance of every connected peripheral.
Do not treat the ATSAM4S8BA-ANR as a drop-in substitute for the ATSAM4S8BA-UUR. Although both are ATSAM4S8BA-family devices, the former is offered in 64-LQFP and the latter in 64-UFBGA WLCSP. Moving between them requires a new land pattern, routing revision, assembly process assessment, and a fresh signal-integrity and power-integrity review.
Assign clock, programming, reset, and communication nets from the exact manufacturer ball map. Keep high-speed or switching-current paths away from external crystal and precision measurement circuits, and provide a quiet return path beneath sensitive analog sections where the package permits. Because a fine-pitch WLCSP offers limited escape-routing space, review layer transitions and via placement before committing to a component position.
