Frequently Asked Questions
What is the maximum clock frequency and propagation delay of the PAL22V10Z-25CJTL?
The PAL22V10Z-25CJTL supports a maximum clock frequency of 50 MHz and has a propagation delay of 25ns, as indicated by the '-25' speed grade in the part number. This performance is sufficient for classic glue logic, address decoding, and state machine applications typically found in legacy embedded and industrial systems.
How many inputs and outputs does the PAL22V10Z-25CJTL have?
The PAL22V10Z-25CJTL provides 11 dedicated inputs, 10 bidirectional I/O lines, and 10 output macrocells. Each macrocell can be configured as a registered (flip-flop) or combinatorial output with selectable output polarity, giving designers flexibility to implement a wide variety of logic functions and state machine configurations.
What package does the PAL22V10Z-25CJTL use and what does the ceramic package mean for reliability?
The PAL22V10Z-25CJTL is housed in a 24-pin ceramic DIP (CDIP, JESD-30 code R-GDIP-T24). Ceramic DIP packages offer superior hermetic sealing and temperature stability compared to plastic DIP packages, making them preferred for high-reliability applications in industrial, military, and aerospace equipment operating across extended temperature ranges.
Is the PAL22V10Z-25CJTL in-system programmable?
No, the PAL22V10Z-25CJTL is not in-system programmable (ISP). It must be programmed using a dedicated PAL/SPLD programmer before installation. Once programmed, the device retains its logic configuration. For in-system programmable alternatives, designers may consider CPLD devices that support JTAG-based programming.
What are common uses for the PAL22V10Z-25CJTL in modern design work?
The PAL22V10Z-25CJTL is primarily used for maintenance and repair of legacy digital systems originally designed with 22V10 PAL devices. It can also serve as a simple, low-cost alternative to CPLDs in new designs requiring modest programmable logic with fewer than 22 inputs. Its deterministic timing and simple architecture make it straightforward to use without complex design tools.
