It runs at 40 MHz with 128 KB of Flash program memory and 16 KB of RAM, giving it enough headroom for moderate control loops, sensor fusion, and communication stacks without overspending on a higher-tier Cortex-M4 part. The 64-LQFP package provides 54 general-purpose I/O lines, and the peripheral set includes I²S, LVD, POR, PWM, and WDT alongside connectivity options like CSIO, I²C, LINbus, SmartCard, and UART/USART. An internal oscillator and an 8-channel 12-bit ADC are integrated, reducing external BOM count. The supply voltage range of 1.65 V to 3.6 V and an operating temperature range of -40°C to 105°C make it suitable for outdoor telecom, factory-floor sensors, and under-hood automotive modules that must survive thermal cycling and cold starts. ## Memory and speed — what the ratings mean for your BOM 128 KB of Flash and 16 KB of RAM place this MCU in the mid-range density tier for Cortex-M0+ parts. That is enough for a bootloader, a real-time kernel, and a moderate application image. The 40 MHz core speed delivers roughly 40 MIPS on the Cortex-M0+ pipeline, which is adequate for control loops, UART baud rates, and I²C fast-mode plus. If your application requires floating-point or DSP-style filtering, the Cortex-M0+ lacks a hardware FPU — that is a design constraint, not a bug. ## Lifecycle and sourcing posture This part carries an Active lifecycle status and is ROHS3 compliant. There is no last-time-buy notice or NRND flag, so it is safe to qualify into new production runs. The FM0+ series is a mature, widely deployed platform, and Cypress (now part of Infineon) continues to support it with documentation and toolchains.","metaTitle":"S6E1C12D0AGV20000 Cypress ARM Cortex-M0+ MCU, 40 MHz","metaDescription":"S6E1C12D0AGV20000 is a 32-bit ARM Cortex-M0+ MCU from Cypress FM0+ series. 40 MHz, 128 KB Flash, 16 KB RAM, 54 I/O, -40 to 105°C.
