Product details
Overview
PALCE16V8-15JC from Cypress Semiconductor is a Flash-erasable, reprogrammable CMOS PAL device with 16 inputs, 8 I/O pins, 15 ns propagation delay (tPD), active pull-up on data inputs, and PCI compliance. It implements sum-of-products logic with programmable macrocells supporting registered or combinatorial operation per output, used in legacy digital control logic, glue logic replacement, and state machine implementation.
For engineers reviewing the PALCE16V8-15JC datasheet, PALCE16V8-15JC pinout, PALCE16V8-15JC application, or PALCE16V8-15JC equivalent, key selection criteria include tCO (12 ns), tS (12 ns), ICC (90 mA max commercial), macrocell configuration flexibility (CL0/CL1 bits), and Flash-based field reprogrammability without UV erasure.
Technical Context
The PALCE16V8-15JC uses a 64 × 32 programmable AND array feeding eight macrocells, each configurable via 18 architecture bits (2 global + 16 local) to operate as registered or combinatorial outputs with polarity control. Output enable can be sourced externally (OE/I9 pin), internally (first product term), or permanently enabled/disabled.
It supports feedback paths from associated I/O pins, adjacent pins, or internal register outputs, and features Power-Up Reset (all registers initialize LOW), electronic signature (64-bit user memory), and security bit to prevent readback. Its 20-pin DIP package supports industrial temperature range (–40°C to +85°C) at 5 V ±10%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| tPD | 15 ns max - defines worst-case input-to-output delay for timing-critical synchronous logic paths |
| tCO | 12 ns max - critical for clock-to-output timing in registered state machines |
| tS | 12 ns min - minimum setup time required before clock edge for reliable register capture |
| ICC | 90 mA max (commercial) - total supply current at 15 MHz counter test condition, enabling thermal budgeting |
| VCC | 5 V ±10% - compatible with standard TTL/CMOS logic rails; supports industrial voltage tolerance |
| I/O Count | 8 bidirectional I/Os + 8 dedicated inputs - provides flexible pin mapping for glue logic consolidation |
| Macrocell Type | User-programmable (registered/combinatorial, polarity-selectable) - enables single-device implementation of diverse logic functions |
Pinout & Package
Package: 20-pin 300-mil plastic dual in-line package (PDIP), JEDEC MS-001, body width 0.300 inch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and I/O drivers |
| 2–9 | I1–I8 | Dedicated input pins; active pull-up enables direct switch/encoder interface without external resistors |
| 10 | CLK/I0 | Global clock input or dedicated input I0; determines synchronous behavior when used as clock |
| 11 | OE/I9 | Output enable control (active-low) or input I9; enables tri-state control of all I/Os |
| 12–19 | I/O0–I/O7 | Bidirectional I/O pins; each tied to independent macrocell with configurable register/combinatorial mode |
| 20 | VCC | +5 V power supply; decoupling capacitor placement near this pin is mandatory for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Flash reprogrammability | Enables in-system logic updates without UV eraser or socket removal; supports up to 100 programming cycles |
| Programmable macrocell | Each of 8 outputs independently configured as registered or combinatorial with output polarity inversion |
| Product term disable (PTD) | Individual fuse-based disable per product term allows precise logic minimization and power reduction |
| Electronic signature memory | 64-bit user-writable memory space for firmware version tagging, board ID, or calibration data storage |
| Security bit | Prevents unauthorized readback of programmed logic pattern, protecting IP in deployed systems |
Applications
| Industrial PLC I/O Expansion | Legacy System Glue Logic Replacement |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic device applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMD AmPAL16V8-15JC | Pin- and function-compatible second-source; identical AC/DC specs but lacks electronic signature memory and security bit | Acceptable for non-IP-sensitive designs where field reprogramming is not required | Select when lowest-cost sourcing is prioritized and readback protection is unnecessary |
| Atmel ATF16V8C-15PU | Same 20-pin PDIP footprint; Flash-based but with 25 ns tPD (min), no PTD fuses, and different configuration bit layout | Suitable only for non-timing-critical replacements where 15 ns tPD is not mandatory | Choose only if design tolerates 10 ns slower propagation and does not require product-term-level optimization |
Compared with AMD AmPAL16V8-15JC and Atmel ATF16V8C-15PU, the PALCE16V8-15JC uniquely delivers full feature parity-including electronic signature, security bit, and PTD fuses-while guaranteeing 15 ns tPD in industrial temperature range, making it the sole option for secure, timing-critical legacy system sustainment.

FAQ
What programming voltage and equipment are required for PALCE16V8-15JC?
The PALCE16V8-15JC requires 12.5 V programming voltage applied to VCC during programming, with standard JEDEC-compliant programmers such as Data I/O PS-29 or BP Microsystems Model 3000. No UV eraser or special sockets are needed due to on-chip Flash technology, and programming is verified via built-in signature readback (64-bit electronic signature).
Does PALCE16V8-15JC support in-system programming (ISP)?
No, the PALCE16V8-15JC does not support true in-system programming. It requires removal from the target board and insertion into a dedicated zero-insertion-force (ZIF) socket programmer. Programming signals (including 12.5 V VPP) are not routed through standard I/O pins, preventing safe ISP without hardware modification.
How does the security bit affect device functionality after programming?
When the security bit is programmed, all attempts to read back the internal logic pattern return undefined data (0xFF bytes), blocking reverse engineering and unauthorized cloning. The device continues full functional operation-programming, erasing, and logic execution remain unaffected-but read access to configuration memory is permanently disabled.
Can PALCE16V8-15JC emulate a 16R8 device, and what configuration settings are required?
Yes, PALCE16V8-15JC emulates 16R8 using CG0=0, CG1=1, CL0x=0 configuration bits, which set all macrocells to registered output mode with active-low outputs. This matches 16R8's behavior exactly, including pin compatibility and timing (tPD ≤15 ns), and is validated in Cypress Application Note AN-127 for legacy PAL migration.
