FAQ

What is the maximum operating frequency of the HD64F7054FL40N?

The HD64F7054FL40N operates at a maximum system clock frequency of 40 MHz, achieved via internal PLL multiplication of an external crystal or clock source. This frequency defines the upper limit for instruction execution speed, timer resolution, and real-time response capability. The HD64F7054FL40N must be powered with a stable 3.3 V supply and use appropriate decoupling to maintain timing integrity at this rate.

Does the HD64F7054FL40N support in-system programming of its Flash memory?

Yes, the HD64F7054FL40N supports in-system programming (ISP) of its 512 KB on-chip Flash memory using software commands or an external programmer compatible with the SH7054F family. This enables field firmware updates without removing the device from the board. The HD64F7054FL40N implements F-ZTAT™ technology to minimize programming latency and supports sector erase for selective code updates.

What package type is used for the HD64F7054FL40N?

The HD64F7054FL40N uses the FP-208A package: a 208-pin plastic quad flat pack with 0.5 mm lead pitch and 28 mm × 28 mm body size. This package is specified in the SH7054F Hardware Manual (Rev. 3.0) and supports standard surface-mount assembly processes. The HD64F7054FL40N's pinout includes dedicated signals for HCAN, SCI, A/D, and external memory interface, all mapped to this physical layout.

Is the HD64F7054FL40N compatible with the HCAN protocol used in automotive networks?

Yes, the HD64F7054FL40N integrates a Hitachi CAN (HCAN) controller compliant with ISO 11898-1, supporting standard CAN 2.0A/B frames and bit rates up to 1 Mbps. It includes dedicated CANH and CANL pins, error handling registers, and sleep/wakeup functionality required for automotive body control applications. The HD64F7054FL40N's HCAN module operates independently of the CPU core to ensure deterministic message handling.

What are the key differences between HD64F7054FL40N and HD64F7055F25?

The HD64F7054FL40N and HD64F7055F25 share the same SH-2 core and FP-208A package but differ in maximum clock frequency (40 MHz vs. 25 MHz) and on-chip Flash size (512 KB vs. 256 KB). Both support identical peripherals including HCAN, SCI, and A/D. The HD64F7054FL40N delivers higher real-time performance and larger firmware capacity, making it suitable for more complex control algorithms and feature-rich applications than the HD64F7055F25.
