Product details

8-macrocell PLD with 15 ns propagation delay

The Microchip ATF16V8CZ-15JC is an electrically erasable programmable logic device (EE PLD) from the 16V8 series, offering 8 macrocells in a 20-PLCC (J-Lead) package. The 15 ns propagation delay sets the ceiling for combinatorial logic paths — at 5V supply, this part can support system clocks up to around 50 MHz in registered mode, depending on the feedback path and external routing. It is a direct drop-in for legacy 16V8 designs needing a current-production, reprogrammable alternative to OTP or UV-erasable parts.

5V supply, J-Lead footprint — board fit

The 20-PLCC (J-Lead) package (supplier device package 20-PLCC 9x9 mm) is a surface-mount footprint with J-shaped leads that provide a larger solder fillet and better thermal-cycle fatigue life compared to gull-wing leads — relevant for industrial environments with wide temperature swings. The device operates from a single 5V supply rail, matching legacy 5V logic families (TTL, HC, HCT). Decoupling: place a 0.1 µF ceramic cap within 5 mm of each VCC/GND pin pair.

For BOM planning, the active status also implies ongoing factory support for programming services and future date-code availability.

Frequently asked questions

Is ATF16V8CZ-15JC compatible with ATF16V8B?

The ATF16V8CZ-15JC and ATF16V8B share the same 16V8 architecture and 20-pin PLCC footprint, but they differ in programming algorithm and timing. The CZ suffix indicates a low-power variant with a 15 ns speed grade. Check the Microchip programming specification to confirm your programmer supports the ATF16V8CZ device ID before substituting.

What is ATF16V8CZ-15JC's listed speed?

The propagation delay is 15 ns. This is the tPD from input to combinatorial output at 5V supply and 25°C. For registered (clocked) operation, the maximum clock frequency is typically around 50 MHz, limited by the internal feedback path and setup time.
