Introduction

R5F72145BDFA#V1 is a microcontroller. It belongs to the family of Renesas 8-bit microcontrollers which operate with a maximum frequency of 12 MHz. It has a 0.18 μm process technology with 86 pins and comes in a large LFBGA package.

Application Field

R5F72145BDFA#V1 is suitable for a wide range of applications like smart phone, tablets, wearable devices and home appliances. The 8-bit microcontroller comes with on-chip data flash and multiple serial communication interfaces so it can be used for device communication in complex networking applications. The integrated peripheral blocks such as Pulse Width Modulation (PWM), Low-Voltage Detect (LVD) and Serial Communication (SCI) simplify the design process and reduce development time. It also can be used to control peripheral devices like image sensors and analog to digital convertors with its flexible Multifunctional Timer Output (MFT) interface.

Working Principle

R5F72145BDFA#V1 is designed to operate with a minimum power consumption. It has four main operating modes including Normal, STOP, WAIT and WAIT-Time for advanced power saving application. In the Normal mode, it runs at the maximum frequency of 12 MHz. In the STOP mode, it reduces the power consumption to 2µA. In the WAIT mode, it can run with as low as 1Ω power consumption. The WAIT-Time mode allows the processor to enter an idle mode for very low power consumption.The processor also uses the low power consumption Multi-Speed Mode (MSM) to automatically regulate the processor frequency and voltage. In the MSM mode, the frequency can range from 4 MHz to 10 MHz and the voltage can range from 1.6V to 3.6V. The voltage level is monitored by the Voltage Monitor (VMON) and Voltage Drop Detection (VddD) sensors on-chip to ensure best energy efficiency.

Conclusion

R5F72145BDFA#V1 is an 8-bit microcontroller suitable for a variety of applications. It features on-chip data flash, integrated peripheral blocks and advanced low-power modes for improved power efficiency. The microcontroller also comes with a Multi-Speed Mode (MSM) to adjust the frequency and voltage automatically to the application\'s needs. The integrated Voltage Monitor (VMON) and Voltage Drop Detection (VddD) sensors ensure best energy efficiency and longer device lifetime.
