Renesas R7FA4E2B92CBB#BC0

Overview

R7FA4E2B92CBB from Renesas is a 32-bit Arm® Cortex®-M33 microcontroller operating at up to 100 MHz, featuring 128 KB code flash, 4 KB data flash, and 40 KB SRAM. It integrates USB Full-Speed, CAN FD, I3C, dual SPI, dual SCI, SSIE, CEC, 12-bit ADC/DAC, temperature sensor, TrustZone security, and operates from 2.7–3.6 V across –40°C to +85°C - deployed in industrial HMI, motor control gateways, and secure IoT edge nodes.

For engineers reviewing the R7FA4E2B92CBB datasheet, R7FA4E2B92CBB pinout, R7FA4E2B92CBB application, or R7FA4E2B92CBB equivalent, key selection considerations include its BGA64 (5 mm × 5 mm) package, -40°C to +85°C temperature grade, absence of USBFS (vs. R7FA4E2B93CBB), and identical peripheral set otherwise - critical for footprint-constrained, thermally stable embedded designs requiring CAN FD and I3C interoperability.

Technical Context

The R7FA4E2B92CBB implements Armv8-M architecture with TrustZone, dual MPU instances (8 regions each for Secure/Non-secure), and two SysTick timers clocked by LOCO or system clock. Its memory subsystem includes ECC-protected SRAM segments and 100,000-cycle data flash endurance.

Connectivity centers on one CAN FD controller (4 TX / 32 RX buffers), one I3C interface compliant with MIPI I3C subsets, and two SCI modules supporting UART, smart card, and Manchester modes - all linked via Event Link Controller (ELC) for CPU-free peripheral coordination.

FAQ

Does R7FA4E2B92CBB support USB Full-Speed functionality?

No, R7FA4E2B92CBB does not include the USBFS module. This is confirmed in Table 1.13 of the R01DS0413EJ0150 datasheet, which explicitly lists "No" under USBFS for R7FA4E2B92CBB. The pinout includes USB_DP/USB_DM pads, but they are unconnected internally. For USB capability, select R7FA4E2B93CBB instead - the only functional difference between those two variants.

What is the operating temperature range of R7FA4E2B92CBB?

R7FA4E2B92CBB is rated for an operating temperature range of –40°C to +85°C, as specified in Table 1.12 and Figure 1.2 of the datasheet. This distinguishes it from the +105°C variant R7FA4E2B93CBB and confirms its qualification for commercial and industrial environments excluding extended-temperature deployments.

Which package type does R7FA4E2B92CBB use?

R7FA4E2B92CBB uses a 64-pin BGA package with part code PLBG0064KB-A, measuring 5 mm × 5 mm with 0.5 mm pitch and an exposed die pad. This matches the "BB" suffix in the part number and is documented in Table 1.12 and Figure 1.4 (Pin assignment for BGA 64-pin) of the R7FA4E2B92CBB datasheet.

Does R7FA4E2B92CBB include CAN FD support?

Yes, R7FA4E2B92CBB includes a full CAN FD module compliant with ISO 11898-1, supporting both classical CAN and CAN FD frames up to 5 Mbps. It provides 4 transmit buffers and 32 receive buffers, as stated in Table 1.7 and confirmed in the "Communication interfaces" section of the R01DS0413EJ0150 datasheet.

How many general-purpose I/O pins does R7FA4E2B92CBB provide?

R7FA4E2B92CBB provides 45 general-purpose I/O pins, as listed in Table 1.11 for the 64-pin BGA variant. These include 5 dedicated input-only pins, 46 pull-up resistor options, 45 N-channel open-drain outputs, and 11 pins with 5-V tolerance - enabling flexible interfacing with legacy and mixed-voltage peripherals.
