FAQ

What is the maximum operating frequency of the R4F2164VTE34V?

The R4F2164VTE34V supports a maximum CPU clock frequency of 33 MHz, achieved using its on-chip PLL with external crystal input (1–8 MHz). This frequency enables sub-100 µs interrupt latency and real-time execution of control algorithms. The R4F2164VTE34V maintains timing accuracy across its full industrial temperature range (−40°C to +85°C) without derating.

Does the R4F2164VTE34V include a built-in CAN controller?

Yes, the R4F2164VTE34V integrates a full CAN 2.0B controller compliant with ISO 11898-1, supporting bit rates up to 1 Mbps and 16 configurable message objects with hardware ID filtering. This eliminates the need for an external CAN transceiver IC-only a physical-layer transceiver (e.g., TJA1040) is required. The R4F2164VTE34V's CAN module supports both standard and extended frame formats.

What package type and pin count does the R4F2164VTE34V use?

The R4F2164VTE34V is housed in a 100-pin LQFP package measuring 14 mm × 14 mm with 0.5 mm lead pitch. It features an exposed thermal pad for enhanced heat dissipation and includes dedicated pins for CAN differential signaling (CAN_TX/CAN_RX), multiple SCI interfaces, and 16-channel 10-bit ADC inputs. The R4F2164VTE34V's pin assignment is fully documented in Renesas Hardware Manual REJ09B0429.

Is the R4F2164VTE34V supported for in-circuit debugging?

Yes, the R4F2164VTE34V includes Renesas' On-Chip Debug Support (OCDS), enabling non-intrusive debugging via JTAG or dedicated debug pins. Engineers can perform real-time register inspection, hardware breakpoints, flash programming, and trace analysis using Renesas E1/E20 emulators. The R4F2164VTE34V's OCDS implementation complies with IEEE 1149.1 and supports both development and field firmware updates.

What is the flash memory endurance specification for the R4F2164VTE34V?

The R4F2164VTE34V specifies 10,000 write/erase cycles for its 256 KB on-chip flash memory, with data retention guaranteed for 20 years at +85°C. Sector-level erase and byte/page programming are supported, and flash security features include read-out protection and write lock bits. These characteristics make the R4F2164VTE34V suitable for applications requiring field-upgradable firmware and long-term reliability in unattended operation.
