Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2372 | No 'R' suffix; lacks EXDMAC, reduced DTC capability, and no IrDA PHY support | Suitable only for cost-sensitive, non-IrDA, non-external-memory applications | Select HD64F2372 only if EXDMAC, IrDA, or advanced bus timing features are unnecessary |
| H8S/2374R | Same family, but 256 KB ROM, 16 KB RAM, and fewer TPU channels (2 vs. 4) | Better fit for space-constrained designs where full 512 KB ROM and 4-channel TPU are unused | Choose H8S/2374R when memory and timer resources can be scaled down to reduce PCB area and cost |
Compared with DF2372RVFQ34V, HD64F2372 omits critical peripherals for modern industrial interfaces, while H8S/2374R trades capacity for footprint - both require firmware and pinout review due to non-drop-in differences in memory map and peripheral register layout.

FAQ
What is the maximum operating frequency of the DF2372RVFQ34V?
The DF2372RVFQ34V supports a maximum system clock frequency of 33 MHz. This rating is specified under standard operating conditions (VCC = 3.3 V ± 0.3 V, TA = –20°C to +75°C) and enables instruction execution at ≤30 ns per cycle. The actual achievable frequency depends on external clock source stability, PCB layout, and decoupling - Renesas recommends verifying timing margins using the hardware manual's setup/hold tables.
Does the DF2372RVFQ34V include a built-in CAN interface?
No, the DF2372RVFQ34V does not include a CAN controller or physical layer transceiver. Its serial communication peripherals are limited to SCI (UART mode) and IrDA physical layer support. CAN functionality would require an external CAN controller (e.g., MCP2515) interfaced via SPI or parallel bus - the DF2372RVFQ34V provides no native CAN protocol handling or message buffering.
What package type and pin count does the DF2372RVFQ34V use?
The DF2372RVFQ34V uses a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch). This is confirmed in Renesas' H8S/2378 Group Hardware Manual Rev.7.00 (2009), which specifies the VFQFPN-144 variant for the 'R' series. The pinout includes dedicated address/data bus lines, interrupt inputs, TPU I/O, and configurable GPIO grouped by port (PA–PE, PH).
Is the DF2372RVFQ34V qualified for automotive applications?
No, the DF2372RVFQ34V is classified as a "Standard" quality grade device per Renesas' documentation and is intended for computers, office equipment, communications gear, test equipment, audio/video, home appliances, and industrial robots. It is not AEC-Q100 qualified and lacks automotive-specific screening, temperature range extension (–40°C to +125°C), or fault-tolerant design features required for automotive ECUs.
How much on-chip flash and RAM does the DF2372RVFQ34V have?
The DF2372RVFQ34V integrates 512 KB of on-chip F-ZTAT™ flash memory and 32 KB of on-chip SRAM. These values are fixed and defined in the memory map for Mode 4 (Expanded mode with on-chip ROM enabled) and Mode 5 (User boot mode), as detailed in Section 3.4 of the Renesas H8S/2378 Group Hardware Manual Rev.7.00.
