The 544 KB flash (544K x 8) and 64 KB RAM (64K x 8) leave headroom for a real-time OS, a USB stack, and a moderate application image without external memory. The wide range means you can drop it into a 5 V legacy bus without a separate regulator for the MCU core. 103 I/O lines are brought out, with connectivity including USB, EBI/EMI (external bus interface for parallel displays or SRAM), I²C, LIN, and multiple UART/USART channels. The EBI/EMI is the key differentiator here — few Cortex-M3 parts in this price band offer a parallel memory bus. ## Active lifecycle and industrial temperature — no obsolescence risk for new designs The part is ROHS3 compliant. It fits factory-floor controllers, outdoor telecom enclosures, and HVAC equipment without a heated enclosure. Package is a 120-LQFP (16×16 mm) — hand-solderable, inspectable, and reworkable with a hot-air station. No BGA reball or X-ray inspection needed. The 0.5 mm pitch fans out on a 4-layer board without microvias. ## Flash-down sibling CY9BF314RPMC-G-JNE2 — same pinout, smaller memory The CY9BF314RPMC-G-JNE2 is the flash-down variant in the same FM3 MB9B310R series. It shares the same 144 MHz Cortex-M3 core, 103 I/O, 120-LQFP package, and peripheral set (USB, EBI/EMI, I²C, LIN, UART). The only difference is program memory: 256 KB vs 544 KB. If your firmware fits in 256 KB, the CY9BF314 drops in without a PCB change.","metaTitle":"CY9BF316RPMC-G-JNE2 Infineon ARM Cortex-M3 MCU, 144 MHz","metaDescription":"Infineon CY9BF316RPMC-G-JNE2 FM3 MB9B310R MCU: ARM Cortex-M3 at 144 MHz, 544 KB flash, 64 KB RAM, 103 I/O, USB, -40 to 85°C.
