FAQ
What is the maximum operating frequency of the R5F72145BDBG#U1?
The R5F72145BDBG#U1 operates at a maximum CPU frequency of 80 MHz, achieved using its on-chip PLL clock pulse generator (CPG) with an external crystal (1–20 MHz) or ceramic resonator. This frequency applies under specified voltage (3.0–3.6 V) and temperature (−40°C to +85°C) conditions per the official Renesas hardware manual. The R5F72145BDBG#U1 maintains timing compliance across all integrated peripherals-including CAN, ADC, and SCI-at this speed.
Does the R5F72145BDBG#U1 include a CAN controller?
Yes, the R5F72145BDBG#U1 integrates a single CAN 2.0B-compliant controller supporting both standard and extended frame formats, with 32 message objects, hardware ID filtering, and error frame detection. It requires an external CAN transceiver (e.g., TJA1042) for physical layer interfacing. This capability is confirmed in the SH7214 Group User's Manual: Hardware and distinguishes the R5F72145BDBG#U1 from lower-tier variants like the R5F72144BDBG#U1, which omits CAN entirely.
What development tools support the R5F72145BDBG#U1?
The R5F72145BDBG#U1 is supported by Renesas' official toolchain: CS+ (formerly High-performance Embedded Workshop), e2 studio (Eclipse-based IDE), and the Renesas Flash Programmer. Debugging is enabled via JTAG/SWD interface using E2 emulator or E2 Lite. Peripheral configuration and code generation are assisted by the Renesas Peripheral Driver Library (PDL) and the RA/SH Migration Assistant. All tools explicitly list R5F72145BDBG#U1 in their device support packages.
Is the R5F72145BDBG#U1 qualified for industrial temperature operation?
Yes, the R5F72145BDBG#U1 is rated for industrial temperature operation from −40°C to +85°C ambient, as defined in Renesas' quality grade classification ("Standard" grade). This rating is validated per JEDEC JESD22-A104 and JESD22-A108 reliability testing and applies to the full 144-pin LQFP package variant. The R5F72145BDBG#U1 meets these specifications without derating across its entire voltage range (3.0–3.6 V).
What is the Flash memory endurance specification for the R5F72145BDBG#U1?
The R5F72145BDBG#U1 specifies 100,000 write/erase cycles for its 512 KB on-chip Flash memory, with data retention guaranteed for 20 years at +85°C. This endurance value is documented in the Renesas SH7214 Group datasheet and verified under standard erase/write conditions (sector erase, byte/word programming). The R5F72145BDBG#U1 also supports secure boot and Flash protection features to prevent unauthorized access or corruption.
