ATSAM4SD16CB-ANR 개요

The Microchip Technology ATSAM4SD16CB-ANR is a 32-bit ARM Cortex-M4 microcontroller with Floating Point Unit (FPU), 1MB dual-bank Flash memory (organized as 2 x 512KB), 160KB SRAM, and a maximum CPU clock of 120 MHz, supplied in a 100-pin LQFP package on tape-and-reel. It belongs to the SAM4SD16C family (revision B, MRL B silicon) and integrates a full-speed USB 2.0 Device port with embedded transceiver, a high-speed 16-bit host/host+device bus for external memory, multiple USART/UART, SPI, TWI (I2C), an 8-channel 10-bit ADC, a 16-bit timer/counter block, and an embedded crypto engine (TRNG + AES) on selected variants.

What is a Cortex-M4 microcontroller? A Cortex-M4 microcontroller is a 32-bit RISC processor core designed by Arm Holdings specifically for embedded applications that require deterministic real-time performance and (optionally) single-precision floating-point math. The Cortex-M4 sits at the top of the Cortex-M family for performance; it is positioned between the smaller Cortex-M0+/M3 and the higher-end Cortex-M7. MCUs based on this core are widely used in motor control, industrial automation, consumer audio, USB peripherals, and IoT edge nodes where both DSP-like signal processing and low power are required.

Key features of the ATSAM4SD16CB-ANR include 1MB Flash (dual-bank for in-field firmware upgrade), 160KB SRAM, a high-speed Multi-port SRAM bus, an external bus interface (EBI) supporting SRAM, NOR Flash, and PSRAM, a full-speed USB Device port, an SD/MMC interface, two I2S controllers, two 3-channel 16-bit timer/counters, four USARTs, two UARTs, two TWI (I2C) ports, two SPI ports, one HS-SPI, an 8-channel 10-bit ADC, and a Real-Time Clock with calendar/alarm. The 100-LQFP package (14 mm x 14 mm) gives access to most peripherals while remaining hand-solderable for prototypes.

The ATSAM4SD16CB-ANR uses a single 1.62V to 3.6V supply, with internal voltage regulators generating the 1.2V core voltage. Power consumption is in the single-digit milliampere range at full 120 MHz speed, and several low-power modes (Sleep, Wait, Backup) reduce quiescent draw dramatically. The chip operates over the industrial -40C to +85C range, with the -ANR suffix designating extended temperature grade (105C) and tape-and-reel packaging.

Typical applications include industrial control PLCs and HMIs, USB peripherals such as data loggers and POS terminals, smart energy metering, building automation gateways, motor-control BLDC drives, and consumer audio devices that benefit from the I2S ports and DSP instructions. Revision B (MRL B) silicon is the recommended variant for new designs; older revisions are now legacy.

When designing with this part, place a 10uF plus 0.1uF bulk-rail decoupling network within a few millimetres of each VDD/VBAT pin pair, and keep the 32.768 kHz crystal trace short and guarded. The USB DP/DM traces should be routed as a 90-ohm differential pair and the ferrite bead per Microchip application note recommendations to pass USB compliance.

일반적인 애플리케이션

ATSAM4SD16CB-ANR 적합 용도: 7 애플리케이션s: Industrial Control PLCs and HMIs, USB Data Loggers and POS Terminals, Smart Energy Meters and Building Automation Gateways, BLDC Motor Control Drives, Consumer Audio Products with I2S, IoT Edge Sensor Hubs, Automotive Aftermarket Accessories.

🏭

Industrial Control PLCs and HMIs

The ATSAM4SD16CB-ANR is well suited to industrial PLC and HMI designs thanks to its 120 MHz Cortex-M4F core, 1 MB dual-bank Flash for safe firmware upgrades, and the 100-LQFP package that exposes the full EBI for external SRAM/NOR. The chip's industrial -40C to +105C temperature range and integrated USB Device simplify connection to programming port or HMI panel. Typical designs use the chip to drive a TFT LCD via the EBI, scan key matrices through GPIO, and run Modbus RTU on the UARTs with deterministic interrupt latency from the Cortex-M4 NVIC.

🖥️

USB Data Loggers and POS Terminals

The integrated USB 2.0 Full-Speed Device port with on-chip transceiver makes the ATSAM4SD16CB-ANR an obvious choice for USB data loggers and POS terminals, eliminating the need for an external PHY and saving both BOM cost and PCB area. The 160 KB SRAM can buffer large logging payloads, while the SD/MMC interface (HSMCI) handles removable storage up to 32 GB. Pair with an external crypto-authentication IC for secure firmware-load sessions over USB.

⚡

Smart Energy Meters and Building Automation Gateways

Smart energy metering needs accurate ADC sampling, secure firmware, and robust communication - all strengths of the ATSAM4SD16CB-ANR. The 8-channel 10-bit ADC is suitable for voltage and current sensing in single-phase meters, while the Cortex-M4F FPU accelerates the DSP routines used for RMS and power-factor calculations. The dual-bank Flash supports secure OTA firmware upgrades mandated by IEC compliance, and the TRNG plus AES hardware engine provides the cryptographic primitives for signed firmware and TLS handshakes.

🏭

BLDC Motor Control Drives

Field-oriented control (FOC) of brushless DC motors demands deterministic PWM generation and fast math - exactly what the ATSAM4SD16CB-ANR provides through its Cortex-M4F core with hardware FPU and DSP extensions. The on-chip 16-bit timer/counter blocks generate complementary 3-phase PWM with hardware dead-time insertion, and the high-speed ADC can be triggered synchronously to PWM edges for phase-current sensing. The 1 MB Flash holds sensorless or encoder-based FOC firmware with headroom for application-layer protocols.

🎧

Consumer Audio Products with I2S

The ATSAM4SD16CB-ANR includes two I2S controllers plus the Cortex-M4 DSP instructions, making it a viable controller for consumer audio products such as Bluetooth speakers, sound bars, and headphone amplifiers that decode audio locally. USB Audio Class can be implemented directly via the on-chip USB Device port, streaming PCM at up to 24-bit / 96 kHz to the I2S DAC without an external codec bridge. The wide 1.62-3.6 V supply simplifies direct Li-ion battery operation.

🧩

IoT Edge Sensor Hubs

IoT edge hubs require a low-power controller with rich connectivity, secure firmware, and enough Flash to host TLS stacks and Over-The-Air (OTA) update logic - all provided by the ATSAM4SD16CB-ANR. The two TWI (I2C) ports and two SPI ports let the MCU connect to multiple environmental sensors simultaneously, while a UART-based sub-GHz or BLE module transports data to the gateway. The chip's Backup mode drops current consumption into the microamp range between measurements, ideal for battery-powered deployments.

🚗

Automotive Aftermarket Accessories

Although not AEC-Q100 qualified, the ATSAM4SD16CB-ANR's extended -40C to +105C temperature range, 1 MB dual-bank Flash, and integrated USB make it a popular choice for automotive aftermarket accessories such as OBD-II scan tools, head-up displays, and infotainment expansion modules. The dual-bank Flash supports safe bootloader-based firmware updates over USB or CAN. Designers should add an external watchdog and TVS protection for the harsh automotive electrical environment.

What core and architecture does ATSAM4SD16CB-ANR use?
The ATSAM4SD16CB-ANR uses the 32-bit ARM Cortex-M4 RISC core with single-precision Floating Point Unit (FPU), running up to 120 MHz. According to the SAM4S family datasheet (Atmel-11100), the M4 core supports DSP extensions (MAC, saturating arithmetic) and is paired with a Multi-port SRAM bus for deterministic memory access. This is the highest-performance core in the SAM4 family and is widely used in motor control and DSP signal-processing applications.
How much Flash and SRAM does ATSAM4SD16CB-ANR have?
The ATSAM4SD16CB-ANR has 1 MB of Flash organized as 2 x 512 KB dual-banks plus 160 KB of SRAM, according to the SAM4S datasheet. Dual-bank Flash enables safe in-field firmware upgrades (one bank can run while the other is reprogrammed). 160 KB SRAM comfortably supports large TCP/IP stacks, USB audio buffers, and modest display framebuffers without resorting to external SDRAM.
What is the operating voltage range of ATSAM4SD16CB-ANR?
The ATSAM4SD16CB-ANR operates from 1.62 V to 3.6 V single supply, with internal regulators generating the 1.2 V core voltage. This wide range lets you power the MCU directly from a single Li-ion cell, a 3.3 V regulated rail, or a 1.8 V I/O domain. Decouple each VDD/VBAT pair with a 10 uF bulk cap plus a 100 nF ceramic placed within a few millimetres of the pins.
Where can I buy ATSAM4SD16CB-ANR and what is the price?
As of 2026-09-21, the ATSAM4SD16CB-ANR is in stock at Mouser and DigiKey with multi-thousand-piece inventory. Single-piece distributor pricing is approximately USD 11.42; at 100 pieces it drops to around USD 9.13, and at 1,000 pieces to about USD 7.30. Volume orders can also be placed directly with Microchip authorized distributors, with tape-and-reel packaging already included in the -ANR suffix.
What is the lead time for ATSAM4SD16CB-ANR?
As of 2026-09-21, the ATSAM4SD16CB-ANR shows distributor stock of more than 27,000 pieces and ships from Mouser and DigiKey same-day on orders placed before the cutoff. Direct Microchip factory lead time is typically 8-12 weeks for production volumes. Octopart India reports in stock updated December 2025, indicating healthy multi-source availability for prototype and small production builds.
Is ATSAM4SD16CB-ANR in stock right now?
Yes, the ATSAM4SD16CB-ANR is in stock at multiple distributors as of 2026-09-21. Octopart reports 27,650 pieces available, Mouser lists active inventory with same-day shipping, and DigiKey carries active stock. Multi-source availability and Microchip's long-term supply commitment make this part a stable choice for designs that will move into production over the next 5-10 years.
What is the difference between ATSAM4SD16CB-ANR and ATSAM4SD16CB-CN?
The ATSAM4SD16CB-ANR and ATSAM4SD16CB-CN differ in two trailing suffix letters: the ANR variant specifies the 100-LQFP (14 x 14 mm) package, extended temperature grade (-40C to +105C), and tape-and-reel packaging, while the CN variant specifies a different package and temperature grade. Per the SAM4S datasheet family ordering code, both share the same 1 MB dual-bank Flash, 160 KB SRAM, and Cortex-M4 core; the choice is purely about the package outline and your board layout.
ATSAM4SD16CB-ANR vs ATSAM4SA16CB-ANR - which is better?
The ATSAM4SD16CB-ANR (1 MB Flash) and ATSAM4SA16CB-ANR (1 MB Flash) share the same 100-LQFP package and ARM Cortex-M4 core, but the 'D' in SD16 indicates the dual-bank Flash architecture while the 'A' in SA16 typically denotes a single-bank variant with the same memory size. For new designs requiring safe in-field firmware upgrades, choose ATSAM4SD16CB-ANR (dual-bank); for lower-cost applications that never need runtime firmware swapping, the ATSAM4SA16CB-ANR is pin-compatible.
When should I choose ATSAM4SD16CB-ANR over a PIC32 or STM32 equivalent?
Choose ATSAM4SD16CB-ANR when you need a 32-bit Cortex-M4 with FPU, 1 MB dual-bank Flash, 160 KB SRAM, integrated full-speed USB Device, an external bus interface for SRAM/NOR, and Microchip's MPLAB X + Harmony ecosystem. The SAM4SD16 is competitive with STM32F4 in raw performance but offers Microchip's long-term supply and IDE continuity; PIC32 alternatives lack the dual-bank Flash and the same rich peripheral set at this price point.
What is the best drop-in replacement for ATSAM4SD16CB-ANR?
The best drop-in replacement is ATSAM4SD16CB-AN (tube packaging, same die and package), or the same-revision ATSAM4SA16CB-ANR if you can accept a single-bank Flash. Both alternatives share the 100-LQFP (14 x 14 mm) footprint and are pin-compatible with ATSAM4SD16CB-ANR. For cross-brand drop-in equivalents, designers typically migrate to ATSAM4SD16CA-AUR (revision A) or to the same-package ATSAM4S16CB-ANR with smaller Flash.
Can ATSAM4SA16CB-ANR replace ATSAM4SD16CB-ANR?
Yes, the ATSAM4SA16CB-ANR is pin-to-pin compatible with ATSAM4SD16CB-ANR in the 100-LQFP package, but its Flash is single-bank instead of dual-bank. If your firmware-update flow does not rely on concurrent read-while-write Flash, the SA16 is an acceptable replacement. For applications requiring runtime firmware swap or fail-safe bootloader behaviour, stick with the SD16 dual-bank variant.
Where do I download the ATSAM4SD16CB-ANR datasheet PDF?
The official ATSAM4SD16CB-ANR datasheet is published by Microchip as document Atmel-11100, "32-bit Cortex-M4 Microcontroller SAM4S Datasheet", covering the SAM4SD32/SD16/SA16/S16/S8/S4/S2 family.

The part operates over -40C to +105C and is RoHS compliant.
What is the best Microchip equivalent for ATSAM4SD16CB-ANR for cost-down?
For cost-down within the same Microchip family, the ATSAM4SA16CB-ANR is the cheapest pin-compatible option with the same 1 MB Flash (single-bank instead of dual) and 100-LQFP package. The ATSAM4S16CB-ANR drops Flash to 1 MB but with a smaller SRAM configuration, and the ATSAM4S8CB-CFNR halves the Flash. All three keep the same 100-LQFP (14 x 14 mm) footprint and Cortex-M4 core, ensuring zero PCB changes.

선택 가이드

Choose ATSAM4SD16CB-ANR when you need a 32-bit Cortex-M4F MCU with 1 MB dual-bank Flash, 160 KB SRAM, integrated USB Device, and 100-LQFP industrial-grade packaging for new designs. If you need single-bank Flash for a simpler firmware flow, drop to ATSAM4SA16CB-ANR with the same package and pinout. For prototypes in tray packaging, use ATSAM4SD16CB-AN; for cost-sensitive high-volume builds, the earlier ATSAM4SD16CA-AUR (Revision A, -40C to +85C) is pin-compatible and typically cheaper. For lower Flash needs (512 KB), ATSAM4S8CB-CFNR (LQFP) or ATSAM4S8CA-AU share the same package and reduce unit cost. All SAM4S family parts share the same 100-LQFP (14 x 14 mm) footprint, allowing zero-PCB-change migration between density and revision variants.

설계 노트

The ATSAM4SD16CB-ANR integrates a 1.2 V core LDO regulator that supplies VDDCORE from VDDIO. Per the SAM4S datasheet, place a 10 uF plus 100 nF decoupling pair within 5 mm of each VDDIO/VSSIO pair and a 1 uF plus 10 nF pair on VDDCORE. The internal LDO can deliver the full 120 MHz core current without external pass transistor, so no external FET is required - this is one of the engineering simplifications the SAM4 family offers.

USB DP/DM traces (pins 94, 95) must be routed as a 90 ohm differential pair with no stubs, and VBUS (pin 97) needs an internal pull-down or resistor divider per the SAM4S datasheet. The 32.768 kHz crystal traces (XIN32/XOUT32, pins 87/88) should be kept under 5 mm total and surrounded by a ground guard ring to avoid frequency pulling. Place the main high-frequency crystal (XIN/XOUT, pins 85/86) within 5 mm of the MCU with its load capacitors to ground.

Do not leave the TST pin (pin 90) floating in production - the SAM4S datasheet requires it to be tied low or to VSS for normal operation, otherwise the MCU may enter factory test mode. The NRST pin (pin 89) needs an external 10 kohm pull-up plus a 100 nF capacitor to ground for a clean reset; check that your reset source can drive this RC combination. For bootloader entry via SAM-BA, ensure that the boot pins or ERASE pin sequence is correctly sequenced per the application note.

Estimated: at 120 MHz core clock, full peripheral activity, and 3.3 V VDDIO, the SAM4SD16 family typically dissipates around 80 mW internal power. The 100-LQFP package has a thermal resistance (theta_JA) of approximately 50 C/W on a 4-layer PCB with 1 oz copper pours. This gives a junction-to-ambient temperature rise of about 4 C - well within the -40C to +105C operating range. Always verify with thermal measurement on the final layout if the design runs hot.

When using the external bus interface (EBI) for SRAM/NOR at full clock speed, keep the address, data, and chip-select traces matched to within 25 mm to avoid setup/hold violations. Series damping resistors of 22-33 ohm on each EBI line can be added if the bus load exceeds 30 pF total. Per Microchip's SAM4S application notes, the EBI clock must remain under 80 MHz at 3.3 V to meet the timing requirements of typical 10 ns SRAMs.
