THIS IS FOR (1 PC) OF PCI1655A-725 BY GI
A Vintage 8-bit Microcontroller PDIP 28 PIN
Architecture: 8-Bit MOS/LSI Program Memory: 512 words of 12-bit Mask ROM (MROM)RAM: 32 bytes of 8-bit registers Package Type: 28-pin Dual In-line Package (PDIP-28)I/O Lines: 20 Input / Output lines Operating Voltage: 4.5V to 7.0V (an improvement introduced by the "A" series to safely support four C-cell batteries
The suffix -725 represents a specific factory-programmed firmware code. Because the PIC1655A utilized a Mask ROM, the software code had to be physically baked into the silicon chip during manufacturing
General Instrument assigned unique 3-digit extension numbers (like -036, -081, or -725) to identify the specific appliance, toy, calculator, or electronic consumer product that the chip was custom-programmed to operate
