Programming the RL78 flash memory using an external device
The RL78 incorporates firmware that controls flash memory programming. The programming to the internal flash memory is performed by transmitting/receiving commands between the programmer and the RL78 via serial communication. There are two ways to program the flash memory in an RL78 using an external device:
- Writing to flash using a flash memory programmer
-
Writing to flash using an external device that incorporates a UART

RL78/L1x
The RL78/L1x microcontroller family is a peripheral rich family of true low power microcontrollers integrating LCD controller/driver, suitable for industrial and consumer LCD display applications. RL78/L1x offer unique display driver functionality to reduce system power consumption.
Low power consumption, compact LCD microcontrollers suitable for small appliances and healthcare devices
RL78/L12 microcontrollers have a built-in segment LCD driver. Three LCD driving voltage generation methods (external resistance division, capacitive split, and internal voltage boost) are supported, corresponding to a variety of segment LCD panels. They realize low current consumption (1): external resistance division: 1.60 μA (2), internal voltage boost: 1.19 μA, and capacitive split: 0.68 µA. With a lineup of 32 to 64-pin products supporting up to 280 segments, these microcontrollers are perfect for small devices with built-in LCD panels such as small appliances and healthcare devices.
(Remarks)(1) Current (typ.) at 1/3 bias, subclock operation, HALT mode, and RTC operation(2) Registance value for external registance division = 1000 kΩ
RL78/L12 MCUs run at up to 24 MHz, consuming just 75 μA/MHz in active mode; 0.64 μA in Halt mode (RTC + LVD); and 0.23 μA in Stop mode (with RAM retention). The LCD circuit adds just another 0.61 μA due to internal voltage boost, a 30% saving over competitive products. The devices resemble an RL78/G13 with less program flash (8-32 KB), SRAM (1.0/1.5 KB), and data flash (2 KB) but comparable low-power and performance specs.
RAM retention:至于关闭模式 (RAM Retention)： 0.1μA，有不少单片机能达到，因为这个就是关闭cpu和外设，只保留RAM供电，没什么技术难度。完全休眠(RAM Retention)模式。

The port function multiplexer（多路复用）, which allows the user flexible pin assignments in regards to peripherals, especially in low pin count versions. For example, on a 30 pin device, if it is desired to use all the PWM outputs outside, then the pin multiplexer, controlled by the Peripheral I/O Reduction Redirection Register PIOR, can be used to have all the timeout PWM outputs connected to output pins.
