This puts it in the mid-range performance tier for Cortex-M3 parts — enough throughput for sensor fusion, motor control loops, or industrial protocol stacks without needing an external memory bus for code. Program memory is 160 KB of on-chip flash, backed by 16K x 8 SRAM. For a typical industrial control application — say, a fieldbus node running a Modbus RTU stack with a few PID loops — that leaves comfortable headroom for the application heap and stack after the HAL and RTOS footprint. ## Peripheral set and I/O count On-chip peripherals include DMA, LVD, POR, PWM, and WDT — the usual complement for autonomous operation without external watchdog or supervisor ICs. Connectivity covers CSIO, EBI/EMI, I²C, LINbus, and UART/USART, giving the designer a choice of serial buses for sensor interfaces, display modules, or legacy fieldbus adapters. 83 general-purpose I/O are brought out to the 100-LQFP package (14x14 mm body). That is a dense pin count for a 100-pin QFP — expect that most of the peripheral muxing shares pins with GPIO, so the actual usable I/O count depends on which serial interfaces are enabled.","metaTitle":"Infineon CY9BF112NPMC-G-JNE2 MCU, ARM Cortex-M3, 144MHz","metaDescription":"Infineon CY9BF112NPMC-G-JNE2 FM3 MB9B110R MCU, 32-bit ARM Cortex-M3 at 144MHz, 160KB Flash, 16Kx8 RAM, 83 I/O, 100-LQFP, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"FM3 MB9B110R","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"144MHz","Series":"FM3 MB9B110R","Package":"Tray","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","Peripherals":"DMA, LVD, POR, PWM, WDT","Connectivity":"CSIO, EBI/EMI, I²C, LINbus, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"83","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"160KB (160K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.7V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.58","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.58000","currency":"USD"},{"qty":10,"price":"$9.55500","currency":"USD"},{"qty":25,"price":"$9.11040","currency":"USD"},{"qty":90,"price":"$7.91033","currency":"USD"},{"qty":270,"price":"$7.55481","currency":"USD"},{"qty":450,"price":"$6.88820","currency":"USD"},{"qty":990,"price":"$5.99940","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/562e5040c012d56b4964b78effa04354.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does Infineon provide for the CY9BF112NPMC-G-JNE2?","answer":"The part is ROHS3 compliant per the manufacturer's declaration.
