R7S721000VCFP#AA1 Présentation
A microprocessor (MPU) is an integrated circuit that integrates a CPU core, memory controllers, and a rich set of peripheral interfaces onto a single die. The RZ/A1H belongs to the broader taxonomy of application processors (CPU core -> application processor -> microprocessor -> embedded processing IC -> semiconductor), sitting above microcontrollers (MCUs) by combining higher CPU frequency with extensive multimedia-oriented peripherals. The on-chip 10 MB SRAM eliminates the need for external SDRAM, simplifying PCB layout and BOM for compact HMI designs.
Key features of the RZ/A1H include dual-display support up to WXGA resolution (1280x800), integrated 2D graphics accelerator, parallel camera interface for image sensor input, hardware JPEG codec, and a wide range of connectivity peripherals including USB 2.0 Host/Function, Ethernet MAC, I2C, SPI, and UART. The single-core Cortex-A9 at 400 MHz delivers approximately 1.0 DMIPS/MHz while keeping power consumption compatible with industrial temperature ranges.
The device architecture pairs the Cortex-A9 core with 32 KB instruction and 32 KB data L1 caches, plus a NEON SIMD engine and a Floating Point Unit (FPU). Its internal bus matrix (AXI/AHB/APB) routes traffic to memory and peripherals with low latency. The 10 MB on-chip SRAM is organized for frame buffer use, supporting two simultaneous displays without external DRAM.
Typical applications include industrial HMI panels, building automation touchscreens, medical patient interface displays, home appliance control panels, point-of-sale (POS) terminals, and portable information terminals. The combination of graphics, camera, and rich connectivity peripherals makes the RZ/A1H ideal for any design that needs a crisp visual interface without external memory complexity.
When designing with this MPU, ensure the PCB thermal pad and power rails deliver stable 3.3 V core/IO supply with adequate decoupling. Designers should reserve sufficient PCB area for the 256-pin LQFP fanout and follow Renesas reference designs to avoid signal-integrity issues on high-speed display and memory interfaces.
This page synthesizes distributor pricing, drop-in alternatives drawn from the same RZ/A1 family, and practical design notes not collected in a single place on the manufacturer datasheet, giving engineers an immediate snapshot for sourcing and reuse.

Notes de conception
The R7S721000VCFP#AA1 draws from a 3.3 V main rail for I/O and internal logic; the Renesas RZ/A1H hardware manual recommends a low-noise LDO plus bulk decoupling on each supply pin and a ferrite bead to isolate any noisy switching converter. Place 100 nF X7R capacitors within 5 mm of every VDD pin and an additional 10 uF on each supply rail for transient suppression.
Estimated: in a 256-LQFP at full 400 MHz CPU load driving dual WXGA, junction temperature rise is modest (a few degrees above ambient) thanks to the plastic package's thermal performance. Use a four-layer PCB with a 2 oz or larger copper pour under the exposed die attach pad to improve thermal conductivity for industrial temperature operation.
The 256-pin LQFP requires careful escape routing on 4-layer PCB at 0.4 mm pitch. Fan out the lower-density pins on the top layer with vias-in-pad only where needed for the inner high-speed display and Ethernet lanes. Follow Renesas RZ/A1H hardware manual reference layouts for display, USB, and Ethernet to avoid signal-integrity issues at 400 MHz operation.
Do not assume other RZ/A1H part numbers are drop-in; some variants change on-chip SRAM size or peripheral set even at the same 256-LQFP package. Cross-check the specific MPN's datasheet against R7S721000VCFP#AA1's peripheral map and memory map before redesigning, and verify boot mode pin settings to ensure correct boot device selection.
