The SH7450 and SH7451 Groups are high-performance RISC microcontrollers embedded with a 32-bit SH-4A CPU core. & They have a maximum operating frequency of 240 MHz, CPU performance of over 432 MIPS, support single and double-precision floating point arithmetic operations, and achieve a maximum single-precision performance of 1.68 GFLOPS. & They incorporate enhanced communication functions required for in-vehicle networks, such as 5 channels of CAN and 2 channels of FlexRay (SH7450). The SH7450 and SH7451 also incorporate camera interface functions required for in-vehicle camera control such as DRI interface (3 channels) and I2C-bus interface (1 channel), and components required for in-vehicle millimeter wave systems such as PDAC, PSEL, and DRI circuits, Timer unit TMU(3 channels), and multifunction timer unit ATU-IIIS (62 channels). Furthermore, an on-chip inter-board communication function for multi-CPU configurations enables higher performance driver-assist systems.
