FAQ

What is the maximum operating frequency of the HD64F7145FW50V?

The HD64F7145FW50V operates at a maximum system clock frequency of 50 MHz, achieved via its on-chip PLL that multiplies an external crystal or clock input. This frequency is fully supported across the specified industrial temperature range (−40°C to +85°C) and enables sub-20 ns instruction cycle times for time-critical control tasks. The HD64F7145FW50V datasheet confirms this rating under DC and AC characteristics sections with no derating required at full temperature span.

Does the HD64F7145FW50V include a CAN controller, and what version does it support?

Yes, the HD64F7145FW50V integrates a CAN controller compliant with ISO 11898-1 (CAN 2.0B), supporting both standard (11-bit) and extended (29-bit) identifier frames at data rates up to 1 Mbit/s. It includes message object buffers, acceptance filtering, and error confinement logic - all documented in the SH7145 Hardware Manual Section 14. The HD64F7145FW50V uses this peripheral for deterministic fieldbus communication in industrial networks without requiring external CAN protocol ICs.

What package type and pin count does the HD64F7145FW50V use?

The HD64F7145FW50V is packaged in a 144-pin LQFP (Low-profile Quad Flat Package) with 0.5 mm lead pitch and 20 mm × 20 mm body dimensions. This package includes an exposed thermal pad for improved heat dissipation during sustained operation. Pin assignments match the SH7145 Group specification, and the HD64F7145FW50V shares identical pinout with other 144-pin SH7145 variants like HD6437145 and HD6417145 - confirmed in the Hardware Manual Section 1.3.

How much on-chip memory does the HD64F7145FW50V provide, and what types are included?

The HD64F7145FW50V includes 256 KB of on-chip Flash memory for program storage and 16 KB of on-chip SRAM for data and stack operations. The Flash supports in-system programming with sector erase and byte-write capability, enabling field firmware updates. All memory is mapped into a unified 32-bit address space, and the HD64F7145FW50V boot process begins at the Flash-resident vector table - verified in the SH7145 Hardware Manual Sections 3.4 and 3.5.

Is the HD64F7145FW50V suitable for automotive applications?

No, the HD64F7145FW50V is classified as a "Standard" quality grade device per Renesas documentation and is intended for industrial, office, and communications equipment - not automotive or safety-critical systems. It lacks AEC-Q100 qualification, extended temperature range beyond +85°C, and automotive-specific fault coverage features. For automotive use, Renesas recommends dedicated RH850 or RL78-Automotive series devices. The HD64F7145FW50V datasheet explicitly excludes transportation equipment in its recommended applications list.
