Product details
Overview
R5F11ZBAAFP#30 from Renesas is a 32-pin LQFP 8-bit RL78/G1P microcontroller designed for ultra-low-power sensor and general-purpose control applications. It delivers 66 μA/MHz active current, 0.31 μA LVD standby, 16 KB flash, 1.5 KB RAM, and integrated 8-channel 12-bit A/D plus dual 10-bit D/A converters - deployed in battery-powered industrial sensors and smart home controllers.
For engineers reviewing the R5F11ZBAAFP#30 datasheet, R5F11ZBAAFP#30 pinout, R5F11ZBAAFP#30 application, or R5F11ZBAAFP#30 equivalent, key selection criteria include its 32-pin LQFP-0.8 mm package, -40°C to +85°C industrial temperature grade (A), 2.7–3.6 V supply, and verified support for UART/I²C/CSI serial interfaces with on-chip debug and self-programming capability.
Technical Context
The R5F11ZBAAFP#30 implements the RL78 CPU core with four 16-bit timer channels (TAU), one watchdog timer, and an event link controller (ELC) enabling hardware-triggered peripheral coordination without CPU intervention. Its clock system combines selectable high-speed on-chip oscillator (1–32 MHz) and external crystal support (1–20 MHz), with independent low-speed 15 kHz oscillator for watchdog operation.
It integrates analog functions including 8-channel 12-bit A/D converter with AVREFP/AVREFM inputs, two 10-bit D/A outputs (ANO0/ANO1), and on-chip voltage detector (LVD) with four threshold levels. Power management includes HALT, STOP, and SNOOZE modes, achieving sub-μA STOP-mode current (0.23 μA typ. at 25°C).

FAQ
What is the maximum operating frequency of the R5F11ZBAAFP#30?
The R5F11ZBAAFP#30 supports a maximum CPU operating frequency of 32 MHz using its high-speed on-chip oscillator. This yields a minimum instruction execution time of 0.03125 μs. External crystal or clock input up to 20 MHz is also supported, with corresponding timing performance detailed in Section 2.4 of the R01DS0371EJ0100 datasheet.
Does the R5F11ZBAAFP#30 support in-system programming?
Yes, the R5F11ZBAAFP#30 supports full in-system programming via its on-chip debug interface and integrated flash library (FSL Type01). It enables rewriting of code flash and data flash memory without removing the device from the PCB - critical for field firmware updates in deployed R5F11ZBAAFP#30-based products.
How many analog input channels does the R5F11ZBAAFP#30 provide?
The R5F11ZBAAFP#30 provides eight 12-bit analog input channels (ANI0 through ANI7), accessible on dedicated pins including P20, P21, P22, P23, P24, P25, P26, and P27. These channels support both single-ended and differential measurement modes using AVREFP and AVREFM reference inputs.
What I²C capabilities does the R5F11ZBAAFP#30 offer?
The R5F11ZBAAFP#30 integrates a single I²C interface (IICA0/IICA1) with dual slave address support - implemented on pins P60 (SCLA0/SCLA1) and P61 (SDAA0/SDAA1). This allows the R5F11ZBAAFP#30 to respond to two distinct 7-bit slave addresses on the same bus, simplifying topology in multi-device sensor networks.
Is the R5F11ZBAAFP#30 qualified for industrial temperature operation?
Yes, the R5F11ZBAAFP#30 is rated for industrial temperature operation from -40°C to +85°C. The "A" in the part number denotes consumer/industrial application grade, and Renesas specifies full electrical performance across this range - confirmed in Section 1.6 and Table 2.3.1 of the R01DS0371EJ0100 datasheet.
