R5F21388ANFP Datasheet | Renesas

Overview 1.1 Features The R8C/38A Group of single-chip MCUs incorporate the R8C CPU core, employing sophisticated instructions for a high level of efficiency. With 1 Mbyte of address space, and it is capable of executing instructions at high speed. In addition, the CPU core boasts a multiplier for high-speed operation processing. Power consumption is low, and the supported operating modes allow additional power control. These MCUs are designed to maximize EMI/EMS performance. Integration of many peripheral functions, including multifunction timer and serial interface, reduces the number of system ponents. The R8C/38A Group have data flash (1 KB × 4 blocks) with the background operation (BGO) function. 1.1.1 Applications Electronic household appliances, office equipment, audio equipment, consumer equipment, etc. REJ03B0274-0120 Rev.1.20 Jul 31, 2010 Page 1 of 57 R8C/38A Group 1.
