The R7F7010184AFP#KA4 contains 1.5 MB of on-chip flash memory with full SEC-DED (Single Error Correction, Double Error Detection) ECC protection. Each 64-bit word includes 8 bits of ECC overhead, enabling automatic correction of single-bit errors and detection of double-bit errors during read operations. Flash programming supports 4 KB sector erase and byte/word write with built-in margin testing and endurance rating of 100,000 cycles. The R7F7010184AFP#KA4 also provides flash access protection via secure boot and region locking.
Is the R7F7010184AFP#KA4 pin-compatible with other RH850/F1KH variants?
The R7F7010184AFP#KA4 uses the 144-pin LQFP package shared with several RH850/F1KH-D8 variants, including R7F7010284AFP#KA4 and R7F7010084AFP#KA4. Pin functions are identical across these parts for core power, reset, clock, JTAG, and primary peripheral signals. However, some secondary function pins (e.g., optional timers or extra ADC channels) may differ in assignment or availability. Always verify pin mapping against the specific variant's datasheet before board reuse. The R7F7010184AFP#KA4 is not pin-compatible with RH850/F1KM series devices.
