ATSAM4S16CA-CFN 概要

The Microchip Technology ATSAM4S16CA-CFN is a 32-bit ARM Cortex-M4 flash microcontroller running at up to 120 MHz with 1024 Kbytes of dual-bank embedded Flash and a 100-ball VFBGA (GREEN, EXT) package.

A 32-bit microcontroller (MCU) is a single-chip computing device that integrates a processor core, memory, and peripherals on one die, forming the lowest layer of the embedded-system hierarchy (microcontroller -> embedded processor -> system-on-chip -> semiconductor device). The SAM4S family belongs to Microchip's (formerly Atmel) ARM-based SAM portfolio and executes the Thumb-2 instruction set with DSP instructions and a Memory Protection Unit (MPU), positioning it between entry-level Cortex-M0+/M3 parts and high-performance Cortex-M7 devices.

Key features include the 120 MHz Cortex-M4 core with hardware MAC and DSP instructions, 1024 KB dual-bank Flash with ECC, Security Bit and lock bits, and pin-to-pin compatibility with the legacy SAM7S, SAM3N and SAM3S series in the 100-pin footprint. Parallel Input/Output (PIO) data capture mode and a full-speed USB Device port round out the peripheral set.

Architecturally, the dual-bank Flash implementation enables safe in-application programming and firmware updates, while the ECC protects stored code against bit corruption. The ARM Cortex-M4 pipeline with single-cycle MAC accelerates digital signal processing such as filtering and FFT-based algorithms common in industrial control.

Typical applications include industrial automation control nodes, consumer and industrial HMI/USB peripherals, and data-acquisition systems that leverage the PIO capture mode and DSP capability.

Design consideration: the VFBGA package demands controlled-impedance PCB layout and proper ball-map fan-out planning; verify power-domain sequencing per the manufacturer datasheet before first power-up.

This page synthesizes distributor pricing from seven sources, drop-in family alternatives, and practical design notes not found in the manufacturer datasheet.

主な用途

ATSAM4S16CA-CFN の用途: 6 件s: Industrial Automation Control Nodes, USB Peripherals and HID Devices, Data Acquisition Systems, Embedded HMI and Display Controllers, Legacy SAM7S/SAM3S Design Upgrades, Motor Control and Digital Power.

🏭

Industrial Automation Control Nodes

Industrial automation nodes demand deterministic processing, robust code storage, and long-term availability, all of which the ATSAM4S16CA-CFN delivers. The 120 MHz ARM Cortex-M4 core with hardware DSP instructions executes PID loops and digital filtering for motor and process control, while the Memory Protection Unit isolates the RTOS kernel from application tasks. The 1024 KB dual-bank Flash with ECC stores large control firmware safely, and field updates can be performed from one bank while running from the other. Its industrial temperature grade suits factory-floor enclosures, and pin compatibility with SAM3S eases upgrades of existing SAM3S-based PLC I/O modules without PCB respin.

🔧

USB Peripherals and HID Devices

The embedded full-speed USB Device port makes the ATSAM4S16CA-CFN a strong fit for USB peripherals such as data loggers, test-instrument front ends, and industrial HID panels. Because the USB transceiver is embedded, no external PHY is required, reducing BOM count and board area in the compact 100-ball VFBGA footprint. The 120 MHz Cortex-M4 core with single-cycle MAC sustains USB throughput while running application DSP, such as sensor calibration math. Dual-bank Flash enables field firmware updates delivered over USB, and the Security Bit protects proprietary firmware from extraction in commercial products.

🖥️

Data Acquisition Systems

In multi-channel data acquisition, the ATSAM4S16CA-CFN's Parallel Input/Output (PIO) data capture mode ingests parallel data streams from external ADCs or FPGA front ends without CPU intervention per word, freeing the 120 MHz Cortex-M4 to apply DSP filtering, decimation, and FFT analysis. The 1024 KB dual-bank Flash buffers configuration, calibration tables, and logging payloads, with ECC safeguarding data integrity in electrically noisy environments. The VFBGA package keeps the controller adjacent to analog front-end circuitry in space-limited measurement modules, and industrial temperature rating supports deployment across -40C to +85C environments.

📺

Embedded HMI and Display Controllers

Human-machine interface panels benefit from the ATSAM4S16CA-CFN's combination of large Flash and DSP-accelerated processing. The 1024 KB Flash stores graphics assets, multi-language string tables, and a GUI middleware stack alongside application code, while the 120 MHz Cortex-M4 renders and refreshes segment or small TFT displays with DMA-assisted peripherals. The MPU enables safe separation of the display task from control logic. Dual-bank Flash allows UI firmware and asset updates in the field, a key requirement for industrial HMI products that evolve over a multi-year service life.

🔧

Legacy SAM7S/SAM3S Design Upgrades

Designers maintaining products built on Atmel SAM7S, SAM3N or SAM3S microcontrollers can upgrade to the ATSAM4S16CA-CFN without changing the PCB, because the SAM4S family is pin-to-pin compatible with these legacy series in the 100-pin version per the Microchip datasheet. The upgrade multiplies performance from the SAM7S ARM7TDMI or SAM3S Cortex-M3 clock rates to a 120 MHz Cortex-M4 with DSP instructions and doubles code headroom to 1024 KB of ECC-protected Flash. This makes it ideal for EOL-mitigation of legacy designs while adding modern features such as the full-speed USB Device port.

⚡

Motor Control and Digital Power

The ARM Cortex-M4 core in the ATSAM4S16CA-CFN includes single-cycle multiply-accumulate and DSP instructions that accelerate field-oriented control (FOC) math for BLDC/PMSM motors and digital power loops. Running control algorithms at 120 MHz allows 16-32 kHz PWM interrupt rates with margin, while the MPU protects the real-time control task from communication stack faults. The 1024 KB dual-bank Flash stores compensator tables and firmware-update images safely, and industrial temperature qualification suits motor-drive environments. Refer to Microchip's SAM4S motor-control reference material for peripheral configuration examples.

What is the difference between ATSAM4S16CA-CFN and ATSAM4S16CB-CFN?
Both are SAM4S series Cortex-M4 microcontrollers at 120 MHz, but the 'CB' suffix denotes a higher peripheral/feature variant within the same package family while 'CA' is the standard configuration. Both come in 100-ball VFBGA packages from Microchip Technology with identical package code and industrial temperature range. According to FindIC comparison data, both parts are Active status; always confirm the exact peripheral差异 in the SAM4S datasheet before substituting one for the other in your design.
What is the difference between ATSAM4S16CA-CFN and ATSAM4S16CA-CFNR?
The only difference is packaging: ATSAM4S16CA-CFNR is supplied in Tape & Reel (TR) packing for automated assembly, while ATSAM4S16CA-CFN is supplied in Tray packing. According to FindIC and DigiKey cross-reference data, both are Active, same SAM4S series, same package and same specifications, making the CFNR variant a direct packaging-level substitute for reel-fed SMT lines.
When should I choose ATSAM4S16CA-CFN over other SAM4S variants?
Choose ATSAM4S16CA-CFN when your design needs exactly 1024 KB of dual-bank Flash in the smallest 100-ball VFBGA footprint with industrial temperature rating. If your BOM process uses reel-fed pick-and-place, select the CFNR tape-and-reel variant instead. If 512 KB Flash suffices, a smaller SAM4S8 variant lowers cost; if you need dual-port SRAM with dual-bank flash, consider SAM4SD16 derivatives. The VFBGA package suits space-constrained designs but requires BGA-capable PCB assembly.
Is ATSAM4S16CA-CFN suitable for USB device applications?
Yes. The ATSAM4S16CA-CFN includes a full-speed USB Device port with embedded transceiver, per the Microchip SAM4S datasheet. Combined with the 120 MHz Cortex-M4 core and 1024 KB dual-bank Flash, it supports USB class firmware (CDC, HID, MSC) with headroom for application code. Dual-bank Flash enables safe firmware update mechanisms triggered over USB, a common requirement for field-upgradable USB peripherals.
Can ATSAM4S16CA-AU replace ATSAM4S16CA-CFN?
No, not as a drop-in replacement. The ATSAM4S16CA-AU uses the same silicon (SAM4S16CA, 1 MB Flash, 120 MHz Cortex-M4) but in an LQFP-100 package, whereas the CFN suffix is a 100-ball VFBGA. The ball grid array and leaded QFP have completely different land patterns, so PCB redesign is required. As a true drop-in, use ATSAM4S16CA-CFNR or ATSAM4S16CA-CFU, which share the identical VFBGA footprint.
What is the best drop-in replacement for ATSAM4S16CA-CFN?
The best drop-in replacements are ATSAM4S16CA-CFNR (tray vs tape-and-reel packaging, identical die and package) and ATSAM4S16CA-CFU (same die in the same VFBGA package with a different packing/temp suffix), both per FindIC comparison data. Same-family same-package options ATSAM4S8CA-CFN (512 KB Flash) and ATSAM4SD16CA-CFN (dual SRAM variant) are also pin-compatible within the SAM4S VFBGA family. All are Microchip Active parts.
Where can I download the ATSAM4S16CA-CFN datasheet PDF?
You can download the ATSAM4S16CA-CFN datasheet PDF from Microchip Technology's official document server: the SAM4S datasheet is available at ww1.microchip.com (document Atmel-11100, 32-bit Cortex-M4 Microcontroller SAM4S Datasheet, file 60001419B covers the family). Free datasheet access is also provided by LCSC, Avaq, and FindIC product pages. The PDF is approximately 5.5 MB and covers the full SAM4S family including this 100-pin VFBGA variant.
What is the best Microchip equivalent for ATSAM4S16CA-CFN from other manufacturers?
There is no true cross-brand drop-in equivalent for ATSAM4S16CA-CFN. The 100-ball VFBGA ball map is proprietary to Microchip's SAM4S family; competitor Cortex-M4 MCUs (e.g., STMicroelectronics STM32F4 in BGA packages) have different ball maps and pinouts, requiring PCB redesign. Microchip's own cross-reference tool confirms substitutes come from within the SAM4S/SAM3S-compatible family. For a redesign-tolerant project, parametric filtering by 120 MHz Cortex-M4, 1 MB Flash, industrial grade finds several options.
What are the key specifications of ATSAM4S16CA-CFN that engineers should know?
Key specifications: ARM Cortex-M4 32-bit core at up to 120 MHz with DSP instructions and MPU; 1024 Kbytes dual-bank embedded Flash with ECC, Security Bit and lock bits; full-speed USB Device port; parallel input/output (PIO) data capture mode; 1.2 V/3.3 V supply operation; 100-ball VFBGA GREEN package, industrial temperature grade, tray packing. Per the Microchip SAM4S datasheet, the family is pin-to-pin compatible with SAM7S, SAM3N and SAM3S 100-pin versions, easing legacy upgrades.
Does ATSAM4S16CA-CFN support firmware updates in the field?

主な差別化要因

  • Dual-bank Flash with ECC for fail-safe field updates (vs ATSAM4S8CA-CFN)
  • Identical silicon at zero PCB change (vs ATSAM4S16CA-CFNR)
  • Legacy family upgrade path (vs ATSAM3S8BA-MUR)

設計ノート

The 100-ball VFBGA requires BGA-capable PCB assembly: specify a minimum 4-layer stackup with dedicated ground plane under the ball field, via-in-pad or dog-bone fan-out with 0.2-0.25 mm laser vias, and controlled-impedance routing for the USB D+/D- pair (90 ohm differential). Plan the ball-map escape before finalizing the schematic net assignment. Estimated: a 0.8 mm ball pitch VFBGA-100 typically escapes within 4 routing layers; verify against the manufacturer package outline drawing.

The device operates from 1.2 V (core) and 3.3 V (I/O) domains per FindIC specification data; verify the internal regulator configuration in the SAM4S datasheet before designing the power tree. Decouple each supply ball with 100 nF ceramic capacitors placed within 2 mm of the ball, plus bulk 10 uF per rail. Confirm the VDDCORE/VDDIO sequencing requirement in the datasheet power-up section to avoid latch-up during startup.

Do not confuse packing suffixes when ordering: CFN is Tray, CFNR is Tape & Reel; pick-and-place lines fed from trays need tray handlers. When using dual-bank Flash self-programming, never erase the bank currently executing code, and reserve the Security Bit until final production programming - once set, debug access via JTAG is permanently locked. Finally, confirm industrial temperature rating on your specific order code, since some suffixes denote extended or commercial ranges.
