Product details
Overview
R5F11EB8AFP#50 from Renesas is an 8 KB flash, 1.5 KB RAM RL78/G1G 32-pin LQFP microcontroller with ultra-low-power operation (2.7–5.5 V), 7-channel 16-bit timer array, dual UART, simplified SPI/CSI, and 12-channel 10-bit ADC - deployed in battery-powered sensor nodes and industrial control panels requiring deterministic real-time response.
For engineers reviewing the R5F11EB8AFP#50 datasheet, R5F11EB8AFP#50 pinout, R5F11EB8AFP#50 application, or R5F11EB8AFP#50 equivalent, this page delivers verified electrical specs, validated I/O mapping for 32-pin LQFP, confirmed peripheral resource allocation (TAU, ELC, PGA), and direct alternative part comparisons grounded in Renesas' official RL78/G1G documentation.
Technical Context
The R5F11EB8AFP#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and support for multiply/divide/MAC instructions. It operates across two main clock domains: high-speed on-chip oscillator (1–24 MHz, ±2% accuracy) and external crystal (1–20 MHz), with dedicated low-speed oscillator (15 kHz) for watchdog timing.
Peripherals are orchestrated via the Event Link Controller (ELC), enabling hardware-triggered transfers between 19 event sources and designated functions without CPU intervention. The device integrates a programmable gain amplifier (PGA), two comparators with DAC-referenced thresholds, and supports key interrupt, buzzer output, and BCD correction - all within its -40°C to +85°C industrial temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11EBAAFP#50 | 16 KB flash, same 32-pin LQFP package and peripheral set - no pinout or timing change required. | Required when firmware exceeds 8 KB or future-proofing for feature expansion is needed. | Select R5F11EBAAFP#50 if code growth is anticipated; identical layout and driver compatibility simplify migration. |
| R5F11EFAAFP#50 | 44-pin LQFP variant with 8 KB flash but adds 4-key return (KR0–KR3), 4 extra analog inputs (ANI4–ANI7), and 4 additional I/O pins. | Suitable for designs needing more analog channels or mechanical keypad support without adding external GPIO expanders. | Choose R5F11EFAAFP#50 only if the 44-pin footprint and expanded I/O are acceptable; not drop-in due to package mismatch. |
Compared with R5F11EB8AFP#50, R5F11EBAAFP#50 offers double flash capacity in identical packaging for seamless firmware scaling, while R5F11EFAAFP#50 trades pin count for enhanced analog and keypad integration - making the former ideal for memory-constrained upgrades and the latter for I/O-rich front-panel designs.

FAQ
What is the maximum operating frequency of the R5F11EB8AFP#50 using its internal oscillator?
The R5F11EB8AFP#50 supports a high-speed on-chip oscillator (HOCO) up to 24 MHz with ±2% accuracy across -40°C to +85°C. This enables a minimum instruction execution time of 0.04167 µs. External crystal operation is rated up to 20 MHz. The R5F11EB8AFP#50 does not support frequencies beyond these limits under specified voltage (2.7–5.5 V) and temperature conditions.
Does the R5F11EB8AFP#50 support hardware debugging during production deployment?
No - the on-chip debug function in the R5F11EB8AFP#50 is intended solely for development and evaluation. Renesas explicitly warns against using it in mass-produced devices due to potential flash memory wear-out and unguaranteed reliability. Production units should disable debug interfaces and rely on ROM-based error logging or UART diagnostics instead of the R5F11EB8AFP#50 debug circuitry.
How many analog input channels are accessible on the R5F11EB8AFP#50, and what is their resolution?
The R5F11EB8AFP#50 provides 12 analog input channels (ANI0–ANI3, ANI16–ANI19) with 10-bit resolution. It supports both external references (via AVREFP/AVREFM pins) and an internal 1.45 V reference. The ADC operates across the full 2.7–5.5 V supply range, and temperature sensing is enabled only in HS (high-speed main) mode per the R5F11EB8AFP#50 datasheet.
Can the R5F11EB8AFP#50 drive standard 5 V logic inputs directly from its GPIO pins?
Yes - selected pins (P01, P10, P15–P17, P30, P31, P50) include TTL-compatible input buffers, accepting logic-high thresholds as low as 1.50 V (at 2.7 V VDD) up to 2.2 V (at 5.5 V VDD). However, output voltage levels remain rail-to-rail (VSS to VDD); driving 5 V logic from a 3.3 V-powered R5F11EB8AFP#50 requires external level translation for guaranteed VIH compliance.
What packaging and tape-and-reel options are available for the R5F11EB8AFP#50?
The R5F11EB8AFP#50 is supplied in a 32-pin plastic LQFP (7 × 7 mm, 0.8 mm pitch) with embossed tape packaging (#50 suffix). It is not offered in tray or tube formats. The FP suffix confirms the LQFP package type, and the #50 marking indicates embossed tape - consistent with Renesas' standard ordering nomenclature for the RL78/G1G family.
