CY9AF312KPMC-G-JNCGE2

Product Overview

The Infineon Technologies CY9AF312KPMC-G-JNCGE2 is a 32-bit microcontroller based on an ARM Cortex-M3 core and specified for a 40MHz operating speed. It provides 160KB (160K x 8) Flash program memory, 16K x 8 RAM, and 36 I/O pins in a 48-LQFP (7x7) surface-mount package. The device operates from a 2.7V to 5.5V supply and includes an internal oscillator. Supported connectivity includes CSIO, I2C, LINbus, UART/USART, and USB, while peripheral features include DMA, LVD, POR, PWM, and WDT. Analog input capability is provided by eight 12-bit ADC channels, and the specified operating temperature range is -40°C to 105°C (TA).

Design & Procurement Notes

Design teams should confirm that the 2.7V to 5.5V supply range matches the system rail, the 48-LQFP (7x7) surface-mount package fits the PCB layout, and the -40°C to 105°C (TA) operating range covers the intended environment. The 160KB (160K x 8) Flash and 16K x 8 RAM sizes should be checked against firmware and runtime data needs. The 36 I/O count, internal oscillator, DMA, LVD, POR, PWM, WDT, ADC channels, and CSIO, I2C, LINbus, UART/USART, and USB interfaces should be mapped to the required functions before schematic capture.
