The ABOV Semiconductor A94B114 User Manual provides an overview, features, pin descriptions, and programming instructions for the 8‑bit CMOS microcontroller.
This manual describes the ABOV Semiconductor A94B114, an advanced CMOS single‑chip 8‑bit microcontroller featuring 8 Kbytes Flash, 512 bytes SRAM, a 12‑bit ADC, 16‑bit PWM, internal high‑ and low‑frequency oscillators, and a wide operating voltage range. It includes detailed information on device features, pin assignments, package options, and electrical specifications.
The document also covers development tools such as third‑party 8051 compilers, the OCD2 on‑chip debugger, and programming hardware (PGMPlusLC2, E‑PGM+). Comprehensive register maps, peripheral operation, power‑down modes, and on‑board programming guidelines are provided for designers and firmware engineers.
