FAQ

What is the maximum operating frequency of the R5F10MMGDFB#30?

The R5F10MMGDFB#30 supports a maximum CPU clock frequency of 32 MHz, achievable using the high-speed on-chip oscillator or an external crystal up to 20 MHz with PLL multiplication. This frequency is maintained across the full 1.6 V–5.5 V supply range and ambient temperature of –40°C to +85°C, as specified in the RL78/I1B Hardware Manual Rev.2.30 Section 5.1.

Does the R5F10MMGDFB#30 include hardware AES encryption?

Yes, the R5F10MMGDFB#30 integrates a dedicated hardware AES-128 engine compliant with FIPS PUB 197, supporting ECB, CBC, and CTR modes. It performs encryption/decryption operations independently of the CPU, with key storage protected by lock bits. This capability is documented in Section 2.2.1 of the RL78/I1B Hardware Manual Rev.2.30 and enables secure firmware updates without software overhead.

What LCD configurations does the R5F10MMGDFB#30 support?

The R5F10MMGDFB#30 supports LCD multiplexing up to 4-common × 40-segment configuration using its integrated segment/common driver. It includes internal bias generation and charge pump circuitry, eliminating need for external components. The exact segment mapping and timing parameters are defined in Section 2.2.2 of the RL78/I1B Hardware Manual Rev.2.30, and require configuration of LCD control registers (LCDCR, LCDCR2).

Is the R5F10MMGDFB#30 pin-compatible with other RL78/I1B variants?

Yes, the R5F10MMGDFB#30 shares identical 80-pin LQFP package and pinout with all other 80-pin RL78/I1B devices including R5F10MME, R5F10MMJ, and R5F10MMH. Pin functions are consistent across this group per Section 1.3.1 of the RL78/I1B Hardware Manual Rev.2.30, enabling drop-in replacement where memory and peripheral requirements align.

What is the typical STOP mode current consumption of the R5F10MMGDFB#30?

The R5F10MMGDFB#30 achieves typical STOP mode current of 0.42 µA at VDD = 3.0 V with real-time clock (RTC) enabled and all other peripherals disabled, as measured per RL78/I1B Electrical Characteristics Table 5.2 in the Hardware Manual Rev.2.30. This ultra-low power state supports multi-year battery operation in portable display applications.
