FAQ
What is the maximum operating frequency of the R7FA2L1A93CFM#AA0?
The R7FA2L1A93CFM#AA0 operates at a maximum frequency of 48 MHz using its Arm Cortex-M23 core. This speed is achievable with the high-speed on-chip oscillator (HOCO) or external crystal sources, and is sustained across the full industrial temperature range (-40°C to +85°C) under 1.6–5.5 V supply conditions. The R7FA2L1A93CFM#AA0 maintains timing compliance without derating in typical PCB layouts.
Does the R7FA2L1A93CFM#AA0 support CAN FD or only classical CAN?
The R7FA2L1A93CFM#AA0 implements a classical CAN 2.0B controller compliant with ISO 11898-1, supporting both standard (11-bit) and extended (29-bit) identifiers and up to 32 configurable mailboxes. It does not support CAN FD data rates or protocol extensions. The R7FA2L1A93CFM#AA0 requires an external CAN transceiver (e.g., TJA1042) for physical layer interfacing.
How many capacitive touch channels does the R7FA2L1A93CFM#AA0 support?
The R7FA2L1A93CFM#AA0 integrates the CTSU2 module supporting up to 32 capacitive touch electrodes - confirmed in the RA2L1 datasheet (R01DS0385EJ0160, Table 1.13) for the 64-pin variant. Electrode assignments include TS00–TS16-CFC and TS21–TS35-CFC, with hardware-accelerated scanning and noise cancellation enabling reliable operation in noisy industrial environments. The R7FA2L1A93CFM#AA0 requires no external touch controller IC.
What security features are implemented in hardware on the R7FA2L1A93CFM#AA0?
The R7FA2L1A93CFM#AA0 includes AES-128/256 encryption engines, True Random Number Generator (TRNG), ECC protection for SRAM, flash area protection registers, and independent watchdog timer (IWDT) with dedicated clock source. These features are silicon-verified and documented in the RA2L1 Security Manual (R01UM0152EJ0100). The R7FA2L1A93CFM#AA0 supports secure boot and encrypted firmware updates without external co-processors.
Is the R7FA2L1A93CFM#AA0 pin-compatible with other RA2L1 group members?
Yes - the R7FA2L1A93CFM#AA0 shares identical pinout and peripheral mapping with all RA2L1 64-pin LQFP variants (e.g., R7FA2L1AB3CFM#AA0, R7FA2L1A92DFM#AA0), differing only in flash size (128 KB vs. 256 KB) and temperature grade (-40°C to +85°C vs. +105°C). This enables seamless migration within the same PCB footprint. The R7FA2L1A93CFM#AA0 is not compatible with 48-pin or 80-pin RA2L1 packages due to I/O count and signal assignment differences.
