The 12-bit resolution is adequate for current-sense feedback or temperature monitoring; the 10-bit DAC can drive a simple analog reference or trim voltage. ## Connectivity and serial interfaces Serial connectivity includes CSIO, I²C, and UART/USART. No USB or CAN on this variant — if you need those, look at the FM3 MB9B310R series sibling (CY9BF314RPMC-G-JNE2) which adds USB and LINbus at 144 MHz. ## Lifecycle and compliance The 100-LQFP (14x14 mm) package is a standard footprint, easy to hand-solder or reflow in a rework station — no hot-air station required for a field swap.","metaTitle":"Cypress CY9AFAA1NPMC-G-UNE2 ARM Cortex-M3 MCU, 20 MHz","metaDescription":"Cypress CY9AFAA1NPMC-G-UNE2 32-bit ARM Cortex-M3 MCU, 20 MHz, 64 KB Flash, 12 KB RAM, 84 I/O, 1.8-5.5 V, -40 to 85°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":"FM3 MB9AAA0N","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Speed":"20MHz","Series":"FM3 MB9AAA0N","Package":"Tray","RAM Size":"12K x 8","Core Size":"32-Bit Single-Core","Peripherals":"LCD, LVD, POR, PWM, WDT","Connectivity":"CSIO, I²C, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"84","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Data Converters":"A/D 16x12b; D/A 2x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.62","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.62000","currency":"USD"},{"qty":10,"price":"$8.68600","currency":"USD"},{"qty":25,"price":"$8.28200","currency":"USD"},{"qty":90,"price":"$7.19122","currency":"USD"},{"qty":270,"price":"$6.86800","currency":"USD"},{"qty":450,"price":"$6.26200","currency":"USD"},{"qty":990,"price":"$5.45400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/36dc265ca2d705eb23784f9a95b690c4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is CY9AFAA1NPMC-G-UNE2's core speed?","answer":"The ARM Cortex-M3 core runs at 20 MHz.
