Product details
Overview
R5F10MMEDFB#30 from Renesas Electronics is an RL78/I1B-series 16-bit microcontroller in an 80-pin LQFP package, featuring 512 KB flash memory, 32 KB RAM, and integrated LCD controller supporting up to 40 segments × 8 commons. It operates at up to 32 MHz with ultra-low power consumption (0.52 μA in deep standby mode), targeting battery-powered industrial HMI and sensor interface applications.
For engineers reviewing the R5F10MMEDFB#30 datasheet, R5F10MMEDFB#30 pinout, R5F10MMEDFB#30 application, or R5F10MMEDFB#30 equivalent, key selection criteria include its on-chip 12-bit ADC (26 channels), 16-bit timer array (TAU) with complementary PWM output, LIN bus support, and hardware real-time clock with calendar function - all verified for operation across –40°C to +85°C.
Technical Context
The R5F10MMEDFB#30 implements the RL78 CPU core with 3-stage pipeline and CISC architecture optimized for low-power embedded control. It integrates a 12-bit successive-approximation ADC with sample-and-hold, programmable gain amplifier, and window comparator functionality - all accessible without CPU intervention via event link controller (ELC).
Its peripheral set includes a 16-bit timer array (TAU) with three independent channels supporting input capture, output compare, PWM generation, and dead-time insertion; plus a dedicated 16-bit real-time clock (RTC) with alarm, periodic interrupt, and calendar mode - both powered by separate sub-clock (32.768 kHz) domain for continuous operation during deep standby.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10MPEDFB#30 | 100-pin LQFP variant with identical core/peripherals but expanded I/O (64 GPIO vs. 59), additional UART channel, and 64 KB RAM | Suitable for designs requiring more analog inputs, serial interfaces, or larger firmware buffers - not pin-compatible due to different package | Select when board layout allows 100-pin footprint and application demands higher memory or I/O count |
| RL78/G14 R5F10PLGDFB#30 | Same RL78/I1B family, 80-pin LQFP, but with 256 KB flash, 20 KB RAM, and no integrated LCD controller | Targeted at non-display applications needing lower cost and reduced feature set - lacks segment/common drivers and bias generator | Choose for cost-sensitive sensor nodes or motor controllers where LCD is unnecessary and flash/RAM requirements are lower |
Compared with R5F10MPEDFB#30 and R5F10PLGDFB#30, the R5F10MMEDFB#30 uniquely balances high flash density (512 KB), full LCD integration, and ultra-low-power RTC operation - making it optimal for space-constrained, display-centric industrial devices requiring long-term firmware field updates and calendar-aware scheduling.

FAQ
What is the maximum operating frequency of the R5F10MMEDFB#30?
The R5F10MMEDFB#30 supports a maximum system clock frequency of 32 MHz when using the high-speed on-chip oscillator or external crystal. This frequency is achievable across the full industrial temperature range (–40°C to +85°C) and supply voltage range (1.6 V to 5.5 V). The device also includes a programmable PLL for clock multiplication, enabling flexible clock tree configuration while maintaining timing margin compliance per the RL78/I1B hardware manual Rev.2.30.
Does the R5F10MMEDFB#30 include an integrated LCD controller?
Yes, the R5F10MMEDFB#30 includes a fully integrated LCD controller supporting up to 40 segments and 8 commons in static or multiplexed drive configurations. It features internal bias voltage generation, software-controllable contrast adjustment, and direct connection to SEG/COM pins without external components. This capability is confirmed in Section 1.3.1 (Pin Configuration) and Chapter 4 (LCD Port Functions) of the RL78/I1B Hardware User's Manual Rev.2.30.
What low-power modes does the R5F10MMEDFB#30 support?
The R5F10MMEDFB#30 supports four distinct low-power modes: HALT (CPU halted, peripherals active), STOP (all clocks stopped except sub-clock), DEEP STOP (only RTC and RAM powered), and SNOOZE (selective peripheral wake-up with CPU in wait state). In DEEP STOP mode, the device draws just 0.52 μA while retaining RTC operation and 32 KB RAM contents - a specification verified in the Electrical Characteristics section of the RL78/I1B datasheet.
Is the R5F10MMEDFB#30 pin-compatible with other RL78/I1B variants?
No, the R5F10MMEDFB#30 is not pin-compatible with 100-pin RL78/I1B variants such as R5F10MPE or R5F10MPG due to differing pin counts and signal assignments. However, it shares identical pinout with other 80-pin RL78/I1B devices including R5F10MMG, allowing direct substitution within the same package footprint - provided flash size, RAM, and peripheral enablement match application requirements.
What development tools are supported for the R5F10MMEDFB#30?
The R5F10MMEDFB#30 is supported by Renesas' e² studio IDE with CS+ compiler, PG-FP5 flash programmer, and E2 emulator for debugging. Hardware evaluation is enabled via the YRDKRL78I1B reference kit, which provides access to all 80 pins, onboard debugger, and example projects for LCD, ADC, and LIN functionality - all documented in Application Note R01AN3803E for the RL78/I1B family.
