Microchip Technology AT87LV55-12JI is an 8-bit CMOS microcontroller featuring an 8051 CPU core operating at a maximum clock frequency of 12MHz. This component utilizes One-Time Programmable Read-Only Memory (OTPROM) for program storage, with a capacity of 20K bytes and an 8-bit program memory width. It offers 256 bytes of data RAM and supports a 16-bit address bus. The device provides 32 general-purpose I/O lines and an 8-bit external data bus. Designed for surface mounting, it is housed in a 44-terminal J-bend PQCC package (JESD-30 Code S-PQCC-J44). The AT87LV55 series operates within a supply voltage range of 5.0V to 5.5V in programming mode, with an extended operating temperature range from -40°C to +85°C. Applications include industrial control and consumer electronics.
