ATSAM4SD32CA-CFUR - 120MHz Cortex-M4 2MB Flash MCU | Microchip
MPN: ATSAM4SD32CA-CFUR ✓ Hoạt độngATSAM4SD32CA-CFUR Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals (timers, communication interfaces, ADCs). Cortex-M4 cores add single-cycle DSP and a single-precision FPU, allowing cost-effective signal-processing workloads. The SAM4S series sits in Microchip's mid-performance MCU tier above Cortex-M0+ parts and below Cortex-M7 high-end families, targeting industrial control, smart energy, and connected sensor applications.
Key features of the ATSAM4SD32CA-CFUR include 2 MB on-chip Flash (organized as 2M x 8), 160 KB SRAM, a 16-bit External Bus Interface (EBI) for SRAM/NOR/NAND expansion, a high-speed USB 2.0 Full-Speed (12 Mbps) Device with on-chip PHY, and a 10/100 Ethernet MAC with MII/RMII interface. The part operates from 1.2 V core / 3.3 V I/O rails, and integrates advanced touch sensing (QTouch), a 12-bit ADC, and a hardware cryptographic engine for AES and secure boot.
Designed for industrial-grade reliability, the device supports an ambient temperature range of -40 C to +85 C and is RoHS-compliant. The VFBGA-100 7x7 mm package is footprint-compatible with other SAM4S VFBGA variants, enabling PCB reuse when scaling flash or peripheral mix. Pin-to-pin and software compatibility with the SAM3S Cortex-M3 family provides a smooth upgrade path for performance gains without firmware redesign.
Typical applications include industrial automation controllers, smart grid and metering endpoints, point-of-sale terminals, HVAC controls, and USB/Ethernet-connected sensor hubs. Its DSP instructions and FPU also suit audio front-end processing and motor-control loops using PWM plus ADC triggering.
When designing with this part, allocate careful PCB layout for the VFBGA-100 footprint: 0.5 mm ball pitch requires microvia HDI stack-up and X-ray or rework-station assembly. Decouple every VDD18/VDD33 pin pair with 100 nF ceramic plus bulk 4.7 uF, and provide a low-impedance ground plane under the BGA for thermal dissipation (theta_JA around 25 C/W on a 4-layer JEDEC test board).

Ghi chú thiết kế
The 100-VFBGA 7x7 mm package at 0.5 mm ball pitch requires microvia HDI PCB stack-up. Use 1 oz copper on outer layers with 0.4 mm laser-drilled microvias to inner power/ground planes. Allocate four inner layers for GND and two for VDD18/VDDIO rails to keep power-impedance below 5 mOhm across the BGA field. Refer to the SAM4S datasheet section 3.4 PCB layout recommendations for clearance rules around the exposed balls.
Decouple every VDDIO/VSSC pair with a 100 nF X7R 0402 ceramic placed within 2 mm of the ball, and provide a 4.7 uF X5R bulk cap per quadrant. For VDDCORE (1.2 V), add a 1 uF plus 100 nF pair at each of the four core-supply clusters. Place a ferrite bead between the USB VBUS pin and the internal regulator when designing bus-powered USB applications to suppress inrush transients, per SAM4S datasheet figure 8-7.
Estimated: at full 120 MHz CPU + Ethernet + USB concurrent operation, the VFBGA-100 device dissipates roughly 300-450 mW, producing a junction-rise of approximately 8-12 C on a 4-layer JEDEC test board (theta_JA about 25 C/W). For sealed enclosures without airflow, derate clock to 80 MHz or add a thermal via array under the BGA center ball grid to drop theta_JA toward 15 C/W.
Do not leave the NRST pin floating - tie it through a 10 kOhm pull-up to VDDIO with a 100 nF cap to GND for clean power-on reset. The ERASE pin must be tied to GND through 10 kOhm in production; leaving it floating can trigger unintended Flash erasure. JTAGSEL must be tied to GND for SWD-only debug or to VDDIO for 4-wire JTAG, per the SAM4S datasheet boot mode table.
