The Microchip Technology AT87LV55-12JC is an 8-bit microcontroller featuring an 8051 CPU core and 20 KBytes of One-Time Programmable Read-Only Memory (OTPROM). This CMOS device operates with a maximum clock frequency of 12MHz and supports an address bus width of 16 bits with an 8-bit external data bus. It includes 256 Bytes of data RAM and 32 general-purpose I/O lines. The AT87LV55 series is designed for applications requiring robust 8051 architecture with non-volatile program storage. This component is suitable for deployment in industrial control systems, consumer electronics, and automotive applications. The device operates within a supply voltage range of 5.0V to 5.5V in programming mode and a minimum of 4.5V. It is housed in a 44-terminal PQCC package (JESD-30 Code: S-PQCC-J44) with a terminal pitch of 1.27mm and operates between 0°C and 70°C.
