TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9327BFG TC9327BFG DTS Microcontroller (DTS-21) The TC9327BFG is a 4-bit CMOS microcontroller for single-chip digital tuning systems, featuring a built-in 230-MHz prescaler, PLL, and LCD drivers.

The CPU has 4-bit parallel addition and subtraction instructions (e.g., AI, SI), logic operation instructions (e.g., OR, AN), composite decision and comparison instructions (e.g., TM, SL), and time-base functions.

The package is an 80-pin, 0

TC9327BFG Features

* 4 bit microcontroller for single-chip digital tuning systems.

* Operating voltage VDD = 1.8 to 3.6 V, with low current consumption due to CMOS circuitry (with only the CPU operating when VDD = 3 V, IDD = 100 µA max)

* Built-in prescaler (1/2 fixed divider +2 modulus prescal
