The control MCU uses a high-performance 16-bit CPU core and integrates a high-precision, high-energy efficiency A / D converter for measuring current and voltage. The single-package SiP configuration combines an 8-bit MCU chip and an analog front-end battery protection control chip, which can provide a smaller installation area and reduce the number of external components. The initial calibration operation requires fewer people and staff, so the battery pack can be reduced Production costs.
Renesas Technology mass-produces R2J24020F Group SiP products, which are suitable for lithium batteries supporting smart battery system standards, such as notebook computers and power tools. In order to meet the market's demand for higher battery residual display accuracy, the newly launched R2J24020F Group products integrate a 16-bit MCU to provide higher performance and an A / D converter to improve accuracy.
The R2J24020F Group IC control MCU uses R8C 16-bit CPU core. This R8C is Renesas Technology's R8C Family MCU product, which provides powerful processing performance and low EMI (electromagnetic interference) and high EMS (electromagnetic tolerance). This 16-bit MCU can greatly improve processing performance and provide faster command execution speed. For example, it can shorten the time to transfer from the operating mode to the power saving mode, thereby reducing power consumption.
In order to provide the battery residual display function, it must have the ability to measure the battery current and voltage. Renesas Technology ’s past products used a 14-bit resolution (delta-sigma) A / D in the current integration circuit and a 12-bit resolution A / D converter in the voltage measurement. The R2J24020F Group has greatly improved the resolution of the current integration circuit to 15/16 bits, and the resolution of the voltage measurement A / D converter to 13 bits to obtain a more accurate display of the remaining battery capacity.
R2J24020F Group provides three kinds of chips with built-in flash memory capacity, suitable for storing MCU programs, customers will choose the memory capacity suitable for the size of the software planned for development. When supplying R2J24020F Group products, Renesas Technology can provide a flash memory that contains written customer software programs or blanks.
The product uses a small 48-pin LQFP package (7mm x 7mm), which helps to apply to smaller substrates. The built-in debug emulator of the E8a chip with a single pin interface is suitable for the development environment; only a single pin is required to connect the debugger. During the debugging process, all I / O pins can be used to improve the efficiency of program development. The newly added debugging function can refer to and change the contents of RAM when executing the developer's software, thereby providing higher efficiency.
