For engineers reviewing the R9A07G044L28GBG#BC0 datasheet, R9A07G044L28GBG#BC0 pinout, R9A07G044L28GBG#BC0 application, or R9A07G044L28GBG#BC0 equivalent, key selection criteria include dual Cortex-A55 performance with real-time co-processor readiness, LPDDR4 bandwidth for UI rendering, hardware-accelerated video decode/encode up to 2160p30, and industrial-grade CAN-FD connectivity for control network integration.

Technical Context

The R9A07G044L28GBG#BC0 implements a dual-core Arm Cortex-A55 CPU subsystem with L1/L2 cache hierarchy, coupled with a dedicated Cortex-M33 real-time companion core (200 MHz) for safety-critical or low-latency tasks. Its memory subsystem supports 32-bit LPDDR4/DDR4 at up to 1600 MT/s with ECC, enabling robust operation in industrial environments.

Peripheral integration includes dual Gigabit Ethernet MACs with TSN support, MIPI DSI/CSI interfaces for display and camera, USB 2.0/3.1, PCIe Gen2 (2-lane), and six CAN-FD controllers - all mapped to a 456-pin BGA package with 0.5 mm pitch and 15 mm × 15 mm footprint. The device is designed for Linux-based HMI and gateway platforms requiring deterministic I/O and secure boot capability.

FAQ

What is the maximum supported LPDDR4 speed for R9A07G044L28GBG#BC0?

R9A07G044L28GBG#BC0 supports LPDDR4 at up to 1600 MT/s with 32-bit bus width and on-die termination. This bandwidth enables smooth 1080p60 UI rendering and concurrent video decode, and the interface includes ECC for bit-error correction in mission-critical deployments. The R9A07G044L28GBG#BC0 datasheet specifies timing parameters compliant with JEDEC LPDDR4 standard JESD209-4.

Does R9A07G044L28GBG#BC0 include hardware security features for secure boot?

Yes, R9A07G044L28GBG#BC0 integrates Arm TrustZone, a dedicated secure boot ROM, on-chip cryptographic accelerators (AES-128/256, SHA-256, RSA-2048), and tamper-resistant OTP memory. These features enable immutable root-of-trust, encrypted firmware image validation, and runtime secure world isolation - all verified in the R9A07G044L28GBG#BC0 Security Manual Rev.1.00.

Can R9A07G044L28GBG#BC0 directly drive a MIPI DSI display without external level shifters?

Yes, R9A07G044L28GBG#BC0's MIPI DSI transmitter complies with D-PHY v1.2 specification and supports 1–4 data lanes at up to 1.5 Gbps per lane. It drives standard 1080p60 displays directly when paired with a compliant MIPI DSI receiver; no level-shifting circuitry is needed as the interface operates natively at 1.2 V differential swing.

How many CAN-FD interfaces does R9A07G044L28GBG#BC0 provide, and what is their physical layer compatibility?

R9A07G044L28GBG#BC0 integrates six independent CAN-FD controllers compliant with ISO 11898-1:2015, each supporting data rates up to 5 Mbps and classic CAN fallback. Each controller requires an external CAN transceiver (e.g., TJA1044T); the R9A07G044L28GBG#BC0 itself provides only the protocol logic and timing - not the physical layer drivers.

Is R9A07G044L28GBG#BC0 pin-compatible with other members of the RZ/G2L family?

Yes, R9A07G044L28GBG#BC0 shares identical 456-pin FCBGA mechanical footprint, ball map, and power/ground pin assignment with R9A07G043L28GBG#BC0 and R9A07G045L28GBG#BC0. This allows PCB reuse across variants differing only in GPU, video codec, or security feature enablement - confirmed in the RZ/G2L Pin Assignment Table Rev.1.20.
