ATSAM4S16BB-ANR Übersicht
A microcontroller unit (MCU) integrates a processor core, program memory, data memory, and peripherals on a single chip, sitting at the heart of embedded systems as the central element of the power-management and control hierarchy. The ARM Cortex-M4 architecture targets mid-range embedded control, combining 32-bit processing performance with deterministic real-time behavior and low interrupt latency.
Key features of the ATSAM4S16BB-ANR include the high-performance Cortex-M4 RISC core at 120 MHz, 1 MB of embedded Flash with optional dual-bank implementation and cache memory, and very low power consumption of approximately 200 uA/MHz as stated on the Microchip product page. The supply range of 1.62 V to 3.6 V supports both 1.8 V and 3.3 V systems, and the peripheral set includes a full-speed USB Device port per the SAM4S family datasheet.
The SAM4S series architecture adds a hardware integer multiplier-accumulator (MAC), optional floating-point-style DSP instructions from the Cortex-M4 core, and an embedded 16 KB ROM containing boot loader routines (UART, USB) and IAP (In-Application Programming) routines, simplifying field firmware updates without external programming hardware.
Typical applications include industrial automation and control nodes, consumer appliances, and USB-connected embedded devices, where the combination of 1 MB Flash, 120 MHz throughput, and a USB Device port covers data logging, HMI, and bridging roles. The 64-pin LQFP makes it a natural upgrade or consolidation path within legacy boards.
A key design consideration: the ATSAM4S16BB-ANR is pin-to-pin compatible with the SAM3N, SAM3S, SAM4N, and SAM7S legacy series in the 64-pin version, allowing designers to migrate older designs with a footprint-preserving swap, though software must be recompiled for the Cortex-M4.

Typische Anwendungen
ATSAM4S16BB-ANR ist geeignet für 6 Anwendungs: Industrial Automation and Control, USB Embedded Devices, Consumer Appliances and HMI, Battery-Powered and Low-Power Sensing, Legacy Design Migration, Motor and Actuator Control.
Industrial Automation and Control
The ATSAM4S16BB-ANR fits industrial control nodes where deterministic real-time response and ample program memory are required. Its 120 MHz Cortex-M4 core executes control loops and communication stacks concurrently with interrupt latency low enough for motor and process control timing, while 1 MB Flash accommodates protocol stacks, data tables, and field-updatable firmware. Peripherals per the SAM4S datasheet - UART, SPI, I2C, PWM, and ADC channels - connect drives, sensors, and HMI panels directly. Powered from a 3.3 V industrial rail (1.62 V to 3.6 V range) at about 200 uA/MHz, it keeps standby power low, and the 64-pin LQFP supports reliable, large-pad industrial assembly.
Empfohlen
USB Embedded Devices
For USB-connected data loggers, HID devices, and PC bridges, the ATSAM4S16BB-ANR is a direct fit because the SAM4S family integrates a full-speed USB Device port with an embedded transceiver per the family datasheet. The 16 KB ROM boot loader supports USB programming, so boards can ship unprogrammed and be flashed over USB in production, eliminating external programmers. Its 1 MB Flash stores descriptor tables, configuration sets, and logging buffers, while the 120 MHz core sustains full-speed USB throughput with headroom for application processing. At 200 uA/MHz it also suits bus-powered designs where the host supplies limited current.
Empfohlen
Consumer Appliances and HMI
In appliances, thermostats, and small HMI panels, the ATSAM4S16BB-ANR provides the processing and memory to drive segment or small graphical displays while managing touch inputs and communications. The 120 MHz Cortex-M4 gives responsive user-interface behavior, and the large 1 MB Flash holds localized text, graphics assets, and multiple product configurations in a single SKU. Its 1.62 V to 3.6 V supply accepts common 3.3 V and battery-derived rails, and the GREEN RoHS-compliant LQFP-64 package meets consumer environmental requirements. Legacy SAM7S- and SAM3S-based appliance boards can adopt it without PCB respin thanks to 64-pin pin compatibility.
Empfohlen
Battery-Powered and Low-Power Sensing
The ATSAM4S16BB-ANR suits battery-operated data loggers and sensor nodes where the datasheet-stated consumption of approximately 200 uA/MHz keeps average current small at duty-cycled clock rates. Running the Cortex-M4 core at reduced frequency, the SAM4S peripheral set (UART, SPI, I2C, ADC) samples sensors and transmits results while sleep modes cut current between events. The 1 MB Flash stores long logging histories and boot-time self-test code, and the 16 KB ROM IAP routines permit firmware updates in the field over UART or USB without external tools. Its extended-temperature GREEN package supports outdoor and appliance-adjacent deployments.
Empfohlen
Legacy Design Migration
Boards built around 64-pin SAM7S, SAM3N, SAM3S, or SAM4N microcontrollers can upgrade to the ATSAM4S16BB-ANR without changing the PCB, because the SAM4S datasheet explicitly states pin-to-pin compatibility with these legacy series in the 64-pin version. This preserves the validated land pattern while doubling memory and moving to the 120 MHz Cortex-M4 with DSP instructions. Migration effort concentrates on firmware: recompile for the M4 toolchain, verify peripheral clock configurations, and re-test. The ROM boot loader (UART, USB) and IAP routines simplify reprogramming of existing fielded units during a phased product rollover.
Empfohlen
Motor and Actuator Control
The SAM4S peripheral set - PWM outputs, timers, and ADC - combined with the Cortex-M4's fast multiply-accumulator makes the ATSAM4S16BB-ANR suitable for motor drives, valve actuators, and positioning systems. Running control loops at 120 MHz provides current-loop execution well above switching frequencies typical of small motors, while 1 MB Flash holds multi-protocol fieldbus code (Modbus, CAN-style UART protocols) alongside the control algorithm. The 3.3 V I/O interfaces cleanly to gate drivers and current-sense amplifiers through isolated front ends, and the 64-pin LQFP supplies enough GPIO for quadrature encoders and limit-switch inputs in compact drive boards.

Wichtigste Unterscheidungsmerkmale

- Cortex-M4 performance over legacy cores (vs. ATSAM3S8BA-MUR)
Designhinweise
Power the ATSAM4S16BB-ANR from a regulated 3.3 V rail within the 1.62 V to 3.6 V datasheet range. Decouple each VDD/VDDIO pin pair with 100 nF ceramic capacitors placed within 2 mm of the pins, plus one bulk 4.7 uF to 10 uF capacitor near the device. Estimate: at 120 MHz and 200 uA/MHz the core draws roughly 24 mA, well within typical 3.3 V LDO capability, but verify worst-case I/O loading when driving many GPIOs. Respect VDDCORE/VDDPLL sequencing per the SAM4S datasheet power chapter if using external regulator topologies.
The 64-LQFP (10 x 10 mm) is a standard 0.5 mm pitch surface-mount footprint; reuse of SAM3S/SAM7S 64-pin land patterns is explicitly supported by the datasheet pin-compatibility statement. Keep the USB Device D+/D- traces as a matched 90-ohm differential pair routed directly to the connector with 22-33 ohm series resistors if signal quality is marginal. Provide a solid ground plane under the MCU and avoid routing fast switching signals under the crystal, whose load capacitors should sit close to the XIN/XOUT pins.
Migration from SAM3N/SAM3S/SAM7S in the same footprint is electrically drop-in but not firmware drop-in: the Cortex-M4 requires recompiled code, and peripheral register maps and clock tree (PMC) configuration differ from legacy parts - review the SAM4S datasheet register chapters line by line. Also note the ATSAM4S16BB-ANR (-AN suffix) and -MU suffix parts use different packages; do not substitute a QFN-ordered part onto an LQFP-64 land pattern. Verify the ROM boot loader pin selection (UART or USB) on your board before finalizing production programming jigs.
