Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA4M2AF3CFM | Higher memory (512 KB flash, 128 KB SRAM), additional peripherals (Ethernet MAC, SDHI), same LQFP64 package and pinout. | Targeted at more complex HMI or gateway applications requiring network connectivity or large local storage. | Select when needing Ethernet, larger code space, or SD card support - not drop-in compatible due to different peripheral register maps. |
| R7FA2E2A93CFM | Arm Cortex-M23 core (lower performance), 128 KB flash, 32 KB SRAM, no USBFS or CAN FD, same 64-pin LQFP package. | Suitable for cost-sensitive, lower-bandwidth sensor nodes where USB/CAN FD are unnecessary. | Choose for simplified BOM and lower power in non-USB/CAN applications; pin-compatible but software migration required due to M23 vs M33 ISA differences. |
Compared with R7FA4M2AF3CFM and R7FA2E2A93CFM, the R7FA4E2B93CFM delivers optimal balance of USB/CAN FD connectivity, TrustZone security, and 105°C operation in a compact LQFP64 footprint - making it ideal for mid-tier industrial and automotive edge controllers where feature density and qualification matter more than raw memory size or ultra-low power.

FAQ
What is the maximum operating frequency of the R7FA4E2B93CFM?
The R7FA4E2B93CFM operates at a maximum frequency of 100 MHz using its Arm Cortex-M33 core. This speed is achieved with the internal PLL enabled and supported by the HOCO or MOSC clock sources. The device maintains full peripheral functionality-including USBFS and CAN FD-at this frequency, as verified in the R01DS0413EJ0150 datasheet revision 1.50.
Does the R7FA4E2B93CFM support USB device functionality without an external transceiver?
Yes, the R7FA4E2B93CFM includes an integrated USB 2.0 Full-Speed transceiver. Pins USB_DP and USB_DM connect directly to the USB connector with appropriate ESD protection and termination. No external PHY is required for basic CDC, HID, or MSC class operation - confirmed in Section 1.5 and Table 1.7 of the R01DS0413EJ0150 datasheet.
What package type does the R7FA4E2B93CFM use, and what are its thermal characteristics?
The R7FA4E2B93CFM uses a 64-pin LQFP package (PLQP0064KB-C, 10 mm × 10 mm, 0.5 mm pitch) with Sn-only terminal finish. It is rated for operation from -40°C to +105°C ambient temperature, validated per JEDEC JESD22-A108. The exposed die pad is recommended to be connected to VSS for improved thermal dissipation - detailed in Figure 1.3 and Table 1.12 of R01DS0413EJ0150.
How many analog input channels does the ADC12 support on the R7FA4E2B93CFM?
The ADC12 module on the R7FA4E2B93CFM supports up to 12 analog input channels (AN00–AN11), plus internal sources including the on-die temperature sensor (TSN) and internal reference voltage. Channel selection, sampling time, and trigger sources (software, timer, or external pin) are fully configurable via registers - specified in Table 1.8 and Section 22 of the R01DS0413EJ0150 datasheet.
Is the R7FA4E2B93CFM pin-compatible with other RA4E2 group members in the same package?
Yes, all RA4E2 devices in the 64-pin LQFP package (e.g., R7FA4E2B93CFM, R7FA4E2B92CFM) share identical pinouts and electrical characteristics. Differences are limited to memory size (128 KB vs 64 KB flash) and operating temperature grade (-40°C to +105°C vs -40°C to +85°C), enabling scalable design reuse - confirmed in Table 1.14 and Figure 1.3 of R01DS0413EJ0150.
