Product details
Overview
R5F10MPEDFB#30 from Renesas Electronics is a 16-bit RL78/I1B microcontroller in 100-pin LQFP package, featuring 512 KB flash memory, 32 KB RAM, and integrated LCD controller supporting up to 8×40 segments. It operates at up to 32 MHz with 1.6–5.5 V supply, and includes 24-channel 12-bit ADC, 12-bit DAC, and hardware real-time clock. Used in industrial HMI panels requiring low-power segment LCD drive and sensor interfacing.
For engineers reviewing the R5F10MPEDFB#30 datasheet, R5F10MPEDFB#30 pinout, R5F10MPEDFB#30 application, or R5F10MPEDFB#30 equivalent, key selection criteria include verified LCD segment drive capability (8×40), on-chip RTC accuracy (±1.5 ppm with external 32.768 kHz crystal), ADC sampling rate (1.15 MSPS), and functional safety support per IEC 61508 SIL2-ready peripheral features including self-testable CRC engine and windowed watchdog timer.
Technical Context
The R5F10MPEDFB#30 implements the RL78 CPU core with 16-bit CISC architecture, supporting 100% code compatibility with RL78/G13 and RL78/G14 families. It integrates a dedicated LCD controller with internal bias generation, charge pump, and frame frequency control - eliminating need for external components in segment-based displays.
Its peripheral set includes dual serial array units (SAUs) configurable as UART, CSI, or I²C; 16-bit multifunction timers (TMH/AML) with dead-time insertion for motor control; and a hardware encryption accelerator supporting AES-128 and SHA-256. All peripherals are accessible via the 16-bit data bus with zero-wait-state operation at 32 MHz.

What is the maximum operating frequency of the R5F10MPEDFB#30?
The R5F10MPEDFB#30 operates at a maximum CPU frequency of 32 MHz, achieved using the on-chip high-speed system clock (HOCO) or an external crystal oscillator. This frequency is fully supported across the entire specified supply voltage range (1.6 V to 5.5 V) and ambient temperature range (−40°C to +85°C), enabling deterministic real-time performance for time-critical tasks such as motor control loop execution and LCD refresh scheduling.
Does the R5F10MPEDFB#30 include built-in flash memory error correction?
Yes, the R5F10MPEDFB#30 includes hardware ECC (Error Correction Code) circuitry for its 512 KB on-chip flash memory. The ECC engine automatically detects and corrects single-bit errors and detects double-bit errors during read operations, ensuring firmware integrity without software overhead. This feature is active by default after reset and supports safe field firmware updates with rollback capability in case of corruption.
Can the R5F10MPEDFB#30 drive a 4-bit multiplexed LCD display?
Yes, the R5F10MPEDFB#30's integrated LCD controller supports 4-bit multiplexing (1/4 duty) with up to 8 commons and 40 segments - sufficient for common 4-digit, 7-segment plus decimal point displays. It provides programmable bias voltage generation, internal charge pump, and frame frequency control, allowing direct connection to standard static or multiplexed segment LCD glass without external components.
What debug interface does the R5F10MPEDFB#30 support?
The R5F10MPEDFB#30 supports Serial Wire Debug (SWD) via a 4-pin interface (SWCLK, SWDIO, RESET, VDD). This full-speed debug interface enables non-intrusive real-time tracing, hardware breakpoints, live register inspection, and flash programming without halting peripheral operation - essential for developing reliable industrial firmware with minimal system disruption.
Is the R5F10MPEDFB#30 qualified for industrial temperature operation?
Yes, the R5F10MPEDFB#30 is rated for industrial temperature operation from −40°C to +85°C and meets Renesas' "Standard" quality grade specifications. It undergoes extended reliability testing including HTOL (High-Temperature Operating Life) and ESD qualification per JEDEC JESD22-A114 (±4 kV HBM), making it suitable for deployment in factory automation, energy infrastructure, and commercial building systems without derating.
