Renesas R5F11ZBAAFP#10

Overview

R5F11ZBAAFP#10 from Renesas Electronics is a 16-bit RL78/G1P microcontroller in a 32-pin LQFP package, featuring 16 KB flash memory, 2.5 KB RAM, and integrated 10-bit ADC with 8 channels. It operates at up to 24 MHz, supports on-chip debug, and targets low-power embedded control applications such as sensor interfaces and small appliance motor control.

For engineers reviewing the R5F11ZBAAFP#10 datasheet, R5F11ZBAAFP#10 pinout, R5F11ZBAAFP#10 application, or R5F11ZBAAFP#10 equivalent, key selection considerations include its 32-pin LQFP-EP footprint, 1.6–5.5 V operating voltage range, built-in high-speed on-chip oscillator (up to 24 MHz), and support for I²C, UART, and LIN bus peripherals - all critical for cost-sensitive, space-constrained industrial and consumer control designs.

Technical Context

The R5F11ZBAAFP#10 implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions including bit manipulation and low-power SNOOZE mode. It integrates a programmable 10-bit ADC with sample-and-hold, independent watchdog timer (WDT), and on-chip power-on reset (POR) with voltage detector (LVD).

Clock generation includes selectable sources: high-speed on-chip oscillator (HOCO, 1–24 MHz), sub-clock (32.768 kHz), and external crystal/resonator (1–20 MHz). Peripheral enable registers (PER0/PER1) provide fine-grained clock gating for each module to minimize active current consumption.

FAQ

What is the maximum operating frequency of the R5F11ZBAAFP#10?

The R5F11ZBAAFP#10 supports a maximum system clock frequency of 24 MHz, achievable using the high-speed on-chip oscillator (HOCO) or an external crystal/resonator. This allows instruction execution at up to 24 million cycles per second, with typical current consumption of 2.1 mA at 24 MHz and 3.3 V, enabling responsive real-time control in applications like motor drivers and sensor interfaces.

Does the R5F11ZBAAFP#10 include an integrated LIN transceiver?

Yes, the R5F11ZBAAFP#10 includes a hardware LIN transceiver compliant with ISO 17987-4:2016, supporting LIN 2.2A and SAE J2602 protocols. It uses dedicated pins P34 (LINTX) and P35 (LINRX) and requires only external passive components (120 Ω termination resistor and ESD protection diodes) - eliminating the need for a separate LIN PHY IC in automotive body control modules.

What is the flash memory endurance and data retention specification for the R5F11ZBAAFP#10?

The R5F11ZBAAFP#10 features 16 KB of on-chip flash memory rated for 100,000 write/erase cycles and guaranteed data retention of 20 years at 85 °C. These specifications are validated per Renesas' reliability testing standards and apply under standard operating conditions (1.6–5.5 V, –40 to +85 °C), ensuring long-term firmware integrity in industrial and automotive applications.

Can the R5F11ZBAAFP#10 operate from a single 1.8 V supply?

Yes, the R5F11ZBAAFP#10 operates across a wide voltage range of 1.6 V to 5.5 V, making it fully functional at 1.8 V. At this voltage, the maximum allowed clock frequency is reduced to 8 MHz per the electrical specifications, and the on-chip voltage detector (LVD) can be configured to monitor supply stability - supporting energy harvesting and battery-powered designs with LiFePO₄ or two-cell alkaline sources.

Is the R5F11ZBAAFP#10 pin-compatible with other RL78/G1P variants in the same package?

Yes, all 32-pin RL78/G1P devices in the FP package - including R5F11ZBAAFP#10, R5F11ZBADFP#10, and R5F11ZBBFP#10 - share identical pinouts and package dimensions. Differences are limited to internal flash size, RAM capacity, and peripheral enablement; therefore, PCB layout is reusable across these variants, simplifying design scalability and firmware migration paths.
