Overview

The RL78/G11 microcontroller line-up concept is based on small packages like 10 to 25pin, in small 16KB flash memory and rich analog peripherals such as A/D converters, D/A converters, comparators and PGA and these are configurable as PGA+ADC+VBGR, PGA+CMP, CMP+DAC/VBGR, or PGA+CMP+DAC/VBGR. Using the smart features like DTC and ELC a lot of peripherals can be connected internally to reduce CPU workload and can save overall power consumption. It also supports very low power operation (100 uA @ 1 MHz ) and a high speed 4µs wake up. Available in small 3x3mm² WFLGA , 3x3mm² HWQFN and standard 20pin LSSOP, this MCU line is suitable for sensor application, Lighting/power sources and many small appliances.

  1. SHA-256 library (RL78/G11)

    Hi. I work with the RL78/G11 and I need to calculate HASH in my application. I found that Renesas has personal implementation of the SHA-256 (https://www.renesas.com/eu/en/software-tool/crypto-library). But, I read that this library ...

  2. RL78/G11 Reset pin as I/O

    Hello, I programed several times a R5F1051 device in circuit thru serial port. Finally I set the P125/Reset pin as input and can't re-program the device again(due no rest input). Any chance to erase/reprogram this device ? (I haver an E1 emu too) Thanks

  3. RL78 / G11 LSSOP

    Hi Guys Hope someone could help me in pcb mount pad for LSSOP? Is TSSOP and LSSOP same footprint? but the seated height i think is different.  But when it comes to land size could I use TSSOP recommended land size?    thank you and best regards

  2. If RL78 Accepts External Interrupt Requests That Occur Immediately After Reset

    No, that interrupt request will not be accepted. After a reset, the registers are initialized to the state of no interrupt request and no interrupt processing allowed, and therefore are in a state in which no external interrupt request can be accepted. Refer to the user’s manual of each ...
