Product details
Overview
R5F11Z7AANA#20 from Renesas is a 24-pin RL78/G1P 16-bit microcontroller designed for ultra-low-power sensor and general-purpose control applications, featuring 16 KB flash ROM, 1.5 KB RAM, 2 KB data flash, 6-channel 8/12-bit A/D converter, and 2-channel 10-bit D/A converter, operating at 2.7–3.6 V with HALT/STOP/SNOOZE low-power modes.
For engineers reviewing the R5F11Z7AANA#20 datasheet, R5F11Z7AANA#20 pinout, R5F11Z7AANA#20 application, or R5F11Z7AANA#20 equivalent, key selection considerations include its HWQFN-24 (4 × 4 mm, 0.5 mm pitch) package, consumer-grade temperature range (−40 to +85°C), integrated high-speed on-chip oscillator (up to 32 MHz), and dual serial interfaces (UART + I²C + CSI).
Technical Context
The R5F11Z7AANA#20 implements the RL78 CPU core with 8-bit × 32 register banks and supports both high-speed main mode (1–32 MHz) and low-speed main mode (1–8 MHz), enabling dynamic clock scaling. Its power management includes POR, LVD (2.75–3.13 V, 4-stage), and dedicated low-speed on-chip oscillator (15 kHz) for watchdog operation independent of system clock.
Peripheral integration centers on analog precision and real-time responsiveness: the 6-channel A/D converter supports VDD-referenced operation (2.7–3.6 V), while the event link controller (ELC) enables hardware-triggered peripheral chaining without CPU intervention-critical for deterministic timing in sensor acquisition and actuator control loops.

FAQ
What is the maximum operating frequency of the R5F11Z7AANA#20?
The R5F11Z7AANA#20 supports a maximum CPU operating frequency of 32 MHz using its high-speed on-chip oscillator. It can also run at up to 20 MHz using an external crystal or clock source on X1/EXCLK pins. Minimum instruction execution time is 0.03125 μs at 32 MHz, confirmed in the R01DS0371EJ0100 datasheet Section 1.1 and 2.4 AC Characteristics.
Does the R5F11Z7AANA#20 support in-circuit debugging?
Yes, the R5F11Z7AANA#20 includes an on-chip debug function accessible via TOOL0 (P40), TOOLTxD (P30), and TOOLRxD (P31) pins. This enables full-featured emulation, breakpoint setting, and memory inspection during development. However, Renesas explicitly advises against using this function in mass-produced end products due to flash endurance limitations.
How many analog input channels does the R5F11Z7AANA#20 have?
The R5F11Z7AANA#20 provides 6 analog input channels: ANI0 through ANI3 (on P20–P23), ANI7 (on P27), and ANI16 (on P10). This is specified in the "Outline of Functions" table (Page 9) and confirmed in the 24-pin pin configuration diagram (Page 4) of the R01DS0371EJ0100 datasheet.
What is the purpose of the REGC pin on the R5F11Z7AANA#20?
The REGC pin on the R5F11Z7AANA#20 connects to the internal voltage regulator's stabilization capacitor. It must be externally tied to VSS via a 0.47–1 μF ceramic capacitor-failure to do so risks unstable operation or failure to meet datasheet electrical specifications. This requirement is explicitly stated in the Pin Configuration section (Pages 4–5) and Absolute Maximum Ratings (Page 12).
Can the R5F11Z7AANA#20 generate PWM signals?
Yes, the R5F11Z7AANA#20 supports PWM generation through its 4-channel 16-bit Timer Array Unit (TAU), with three of the four channels capable of PWM output (TO00–TO03). The datasheet confirms "PWM outputs: 3" under the Timer section in the Outline of Functions (Page 9), and pin assignments (e.g., TO00 on P13, TO01 on P16) are defined in the 24-pin pin diagram (Page 4).
