Renesas R5F11Z7AANA#40

Overview

R5F11Z7AANA#40 from Renesas Electronics 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 power modes.

For engineers reviewing the R5F11Z7AANA#40 datasheet, R5F11Z7AANA#40 pinout, R5F11Z7AANA#40 application, or R5F11Z7AANA#40 equivalent, this page delivers verified electrical specs, package mapping to HWQFN-24 (4 × 4 mm, 0.5 mm pitch), confirmed I/O count (20 total, including 2 N-ch open-drain), real-time clock output/buzzer capability, and low-power operation down to 0.31 μA in LVD mode.

Technical Context

The R5F11Z7AANA#40 implements the RL78 CPU core with 8-bit × 32 register banks and supports dual-clock architecture: high-speed on-chip oscillator (selectable 1–32 MHz) and low-speed 15 kHz on-chip oscillator. It integrates a 4-channel 16-bit timer array unit (TAU), UART0, CSI00, I²C bus interface (IICA0/IICA1), and event link controller (ELC) for peripheral synchronization.

Its analog subsystem includes AVREFP/AVREFM reference pins, 6 analog input channels (ANI0–ANI3, ANI7, ANI16), and two analog outputs (ANO0/ANO1), all operating within the 2.7–3.6 V supply range. Power management includes POR, LVD (4-stage detection), and three low-power modes-HALT, STOP, and SNOOZE-with verified current draw of 320–530 μA in HALT and 0.18–3.30 μA in STOP across −40°C to +85°C.

FAQ

What is the package type and pin count of the R5F11Z7AANA#40?

The R5F11Z7AANA#40 uses a 24-pin HWQFN package (4 × 4 mm body, 0.5 mm pitch) with an exposed die pad that must be connected to VSS. This compact footprint supports high-density PCB layouts in space-constrained applications such as wearable sensors and portable medical devices. The R5F11Z7AANA#40 provides 20 total I/O pins, including 2 N-ch open-drain outputs rated to 6 V.

Does the R5F11Z7AANA#40 support self-programming of its flash memory?

Yes, the R5F11Z7AANA#40 supports self-programming of both code flash and data flash memory using on-chip flash libraries (FSL Type01). It includes hardware-level write/erase prohibition for data flash blocks to prevent accidental corruption. Self-programming requires dedicated RAM areas (e.g., FFE20H–FFEFFH) and consumes 2.50–12.20 mA during operation - a value explicitly measured and documented in the R01DS0371EJ0100 datasheet.

What are the key low-power operating modes supported by the R5F11Z7AANA#40?

The R5F11Z7AANA#40 supports HALT, STOP, and SNOOZE modes. HALT draws 320–530 μA at 3.0 V with clocks running; STOP draws 0.18–3.30 μA with all clocks halted except LVD; SNOOZE allows selective peripheral operation during low-power sleep. These modes are validated across −40°C to +85°C and enable multi-year battery life in sensor nodes - a core design objective of the RL78/G1P family.

Can the R5F11Z7AANA#40 generate precise clock or buzzer signals?

Yes, the R5F11Z7AANA#40 features two programmable clock/buzzer outputs (PCLBUZ0 and PCLBUZ1) capable of generating frequencies from 2.44 kHz to 10 MHz - including standard audio tones (e.g., 4.88 kHz) and high-speed logic clocks. These outputs derive from the high-speed on-chip oscillator and require no external components, reducing bill-of-materials in alarm systems and HMI interfaces.

How many analog input and output channels does the R5F11Z7AANA#40 include?

The R5F11Z7AANA#40 includes six analog input channels (ANI0–ANI3, ANI7, ANI16) and two analog output channels (ANO0, ANO1), both implemented as 10-bit D/A converters. All analog functions operate within the 2.7–3.6 V supply range and support AVREFP/AVREFM differential referencing - enabling accurate ratiometric measurements critical in precision sensor applications.
