It carries 16 KB of on-chip Flash program memory, 1.25 KB of RAM, and a separate 4 KB EEPROM block. 34 general-purpose I/O lines are available, along with I²C, SPI, and two UART/USART serial interfaces. On-chip peripherals include a PWM generator, a watchdog timer, and a power-on reset circuit. ## 52-PLCC footprint — board layout and rework notes The part comes in a 52-lead PLCC (J-lead) package, supplier device code 52-PLCC (19.15x19.15 mm). The J-lead form factor is a legacy SMT package that still sees use in high-reliability and retrofit designs because the leads are more robust than fine-pitch QFP. The 0.050-inch pitch requires a standard PLCC-52 footprint; a two-layer board can route all signals if the decoupling caps are placed close to the Vcc/Vss pairs. Rework with a hot-air station is straightforward — the J-leads are visible and accessible for touch-up. The part is ROHS3 compliant.","metaTitle":"AT89C5130A-S3SUM 8-bit MCU, 48 MHz, 16 KB Flash, USB","metaDescription":"Microchip AT89C5130A-S3SUM 8-bit 80C51 MCU, 48 MHz, 16 KB Flash, 1.25 KB RAM, USB, I²C/SPI/UART, -40 to 85°C, 52-PLCC.","metaKeywords":null},"attributes":{"series":"AT89C513x","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Speed":"48MHz","Series":"AT89C513x","Package":"Tube","RAM Size":"1.25K x 8","Core Size":"8-Bit","EEPROM Size":"4K x 8","Peripherals":"LED, POR, PWM, WDT","Connectivity":"I²C, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"34","Core Processor":"80C51","Package / Case":"52-LCC (J-Lead)","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"52-PLCC (19.15x19.15)","Voltage - Supply (Vcc/Vdd)":"2.7V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.68","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.68000","currency":"USD"},{"qty":25,"price":"$8.87800","currency":"USD"},{"qty":100,"price":"$8.04000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a5482a42b14a9f74ab28977184418464.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum clock speed of AT89C5130A-S3SUM?","answer":"The 80C51 core runs at 48 MHz maximum.
