enCoRe™ III Low Voltage CY7C603xx is a powerful Harvard architecture processor that operates at speeds up to 12 MHz. It offers low power, with a operating voltage range of 2.4V to 3.6V, which can be reduced to 1.0V using the on-board switch mode pump (SMP). The device is also designed for commercial temperature range of 0°C to +70°C.
The enCoRe III Low Voltage (enCoRe III LV) CY7C603xx family is a low‑voltage 8‑bit Harvard‑architecture microcontroller with up to 12 MHz CPU speed, 8 KB flash, 512 B SRAM, and configurable analog and digital peripherals. It operates from 2.4 V to 3.6 V (down to 1.0 V using an on‑chip switch) and includes features such as an internal 1.3 V reference, switch‑mode pump, and I²C master/slave up to 400 kHz.
Development is supported by Cypress’s PSoC Designer IDE, which provides a graphical device editor, user‑module library, in‑circuit emulator, and debugger. The IDE runs on Windows platforms and generates C code and configuration files, simplifying hardware configuration and software development for the CY7C603xx devices.
