For engineers reviewing the R7S721001VCBG#AC0 datasheet, R7S721001VCBG#AC0 pinout, R7S721001VCBG#AC0 application, or R7S721001VCBG#AC0 equivalent, key selection criteria include its 400 MHz max CPU frequency, integrated DDR3L memory controller with 16-bit bus width, dual-camera interface support (up to 5 MP), and 256-pin BGA package with 0.65 mm pitch.

Technical Context

The R7S721001VCBG#AC0 implements a dual-core ARM Cortex-A9 MPCore CPU with NEON and VFPv4 extensions, coupled with 256 KB L2 cache and on-chip SRAM (128 KB). Its memory subsystem supports DDR3L-1066 (16-bit bus, 4 Gb addressable) and includes dedicated AXI interconnect for low-latency peripheral access.

It integrates multiple domain-specific controllers: a 24-bit RGB LCD controller with alpha blending, two MIPI CSI-2 receivers (each supporting up to 1.5 Gbps), USB 2.0 HS Host/Device, and a 10/100 Ethernet MAC with RMII/MII interface - all managed via a hierarchical interrupt controller (GIC-400 compatible).

FAQ

What is the maximum operating frequency of the R7S721001VCBG#AC0 CPU?

The R7S721001VCBG#AC0 features a dual-core ARM Cortex-A9 processor with a maximum operating frequency of 400 MHz. This frequency is achievable under specified thermal and voltage conditions (VDDCORE = 1.0 V, junction temperature ≤ 85°C) and is validated across the commercial temperature range (0°C to +70°C). The R7S721001VCBG#AC0 does not support dynamic frequency scaling beyond this rated speed.

Does the R7S721001VCBG#AC0 include an integrated DDR3L memory controller?

Yes, the R7S721001VCBG#AC0 integrates a dedicated 16-bit DDR3L-1066 memory controller supporting up to 4 Gb addressable space. It includes on-die termination, programmable timing parameters, and JEDEC-compliant initialization sequences - eliminating the need for external memory controller logic and reducing signal integrity complexity in the R7S721001VCBG#AC0 design.

What display interfaces does the R7S721001VCBG#AC0 support?

The R7S721001VCBG#AC0 supports a 24-bit RGB parallel LCD interface with dual-channel capability (separate HSYNC/VSYNC/DE per channel), enabling simultaneous drive of main and auxiliary displays. It also includes hardware alpha blending, programmable polarity, and built-in timing generator - no external timing controller is required for standard TFT panels used with the R7S721001VCBG#AC0.

Can the R7S721001VCBG#AC0 interface with MIPI CSI-2 cameras?

Yes, the R7S721001VCBG#AC0 integrates two independent MIPI CSI-2 receivers, each supporting up to 1.5 Gbps per lane (4-lane configuration per interface). This allows direct connection to two separate image sensors - for example, one for visible-light capture and another for infrared - without external bridge chips in R7S721001VCBG#AC0-based vision systems.

What package type and pin count does the R7S721001VCBG#AC0 use?

The R7S721001VCBG#AC0 uses a 256-ball Fine-Pitch Ball Grid Array (FBGA) package measuring 17 mm × 17 mm with 0.65 mm ball pitch and an exposed thermal pad. This package is identical across the RZ/A1H family, ensuring mechanical compatibility and layout reuse for R7S721001VCBG#AC0 and related variants like R7S721021VCBG#AC0.
