SH7146 Series
HD74LS257 Renesas/Hitachi HD74LS257
The SH7146 Series incorporates an SH-2 32-bit RISC (Reduced Instruction Set Computer) CPU core, and offers a maximum operating frequency of 80 MHz, representing a 1.6-fold improvement in performance over the 50 MHz of Renesas Electronics’s current SH7046 Series. HD74LS257 Renesas/Hitachi HD74LS257Featuring an on-chip power supply step-down circuit, these microcontrollers are designed to achieve lower current dissipation by suppressing the increase in current dissipation associated with higher speed, and attain 5 V single-power-supply operation while a high 80 MHz operating frequency.HD74LS257 Renesas/Hitachi HD74LS257
