The 8753H/BQA is an 8-bit microcontroller built around the 8051 CPU core, clocked at 12 MHz. Program memory is UVPROM — one-time factory-programmed, not field-reprogrammable — so the firmware must be finalized before ordering.
The 12 MHz clock drives the 8051 CPU core. UVPROM memory prevents field firmware updates.
Through-hole package (Bulk) suits hand-soldering and socketed boards.
The 8753H/BQA is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock or price figures are published here.
The 8753H/BQA is rated for -55°C to 125°C (TC), suitable for military, aerospace, and downhole applications.
