The 32 KB EEPROM stores calibration coefficients and fault logs, eliminating a separate serial EEPROM from the BOM. The 29-channel 12-bit ADC samples multiple analog inputs — current sensors, thermistors, potentiometers — in a single conversion sequence. The dual 12-bit DAC generates analog setpoints or reference voltages for external regulators or amplifiers. Both converters share the internal oscillator, so no external crystal is required for the conversion clock. ## Ethernet, CAN, USB — industrial gateway and drive connectivity The peripheral set includes Ethernet, CANbus, USB, and QSPI — the three interfaces that dominate industrial communication. Ethernet handles Modbus TCP or EtherNet/IP; CANbus covers CANopen or J1939 on the drive network; USB provides a local programming or data-logging port. The QSPI interface connects to external NOR flash or SRAM for data buffering. The 111 I/O pins leave room for parallel LCD buses, external memory interfaces, and sensor arrays. The EBI/EMI interface allows direct connection to external SRAM, SDRAM, or FPGA dual-port memory without a glue-logic CPLD. For motor-drive applications, the PWM timer channels generate complementary dead-time-controlled outputs for three-phase inverter stages. ## 100-TFLGA 7x7 mm — board integration checklist The 100-TFLGA package measures 7x7 mm with a 0.50 mm ball pitch. This is a land-grid array, not a BGA — the pads are flat lands, not solder balls, so the reflow profile follows the JEDEC LGA standard. The surface-mount footprint requires a solder-paste stencil thickness of 0.125 mm for consistent joint height.","metaTitle":"R5F5651EHGLJ#20 RX651 MCU, 120 MHz, 2 MB Flash, 640 KB RAM","metaDescription":"R5F5651EHGLJ#20 RXv2 32-bit MCU, 120 MHz, 2 MB flash, 640 KB RAM, 111 I/O, Ethernet/CAN/USB, -40 to 105°C, 100-TFLGA.

The R5F5651EHGLJ#20 is the 2 MB flash / 640 KB RAM / 100-TFLGA variant. A lower-memory sibling (1 MB flash, 256 KB RAM) in the same 100-TFLGA package is pin-compatible and can serve as a cost-reduction path if the application fits within the smaller memory footprint.
