The LATTICE ispLSI1016 is a highly reliable programmable logic IC that has been widely deployed in industrial automation, telecommunications, medical electronics, instrumentation, military equipment, communication infrastructure, and embedded control systems. Unlike a traditional microcontroller, this CPLD implements customized digital logic directly in programmable hardware, providing deterministic performance, fast signal processing, and long-term operational stability.

The device became popular because it offered flexible logic integration while reducing component count on complex circuit boards. To safeguard proprietary hardware designs, many manufacturers enabled protective, locked, or encrypted security features that prevent unauthorized access to the programmed logic configuration. As a result, valuable engineering resources remain securely stored within the device, making direct access to internal design information extremely difficult after deployment.

Machines, Address Decoders, etc.As industrial equipment continues operating for decades, companies frequently encounter situations where the original development resources have disappeared while the hardware remains essential for production. In these cases, engineers often require professional services to unlock, crack, readout, dump, decrypt, copy, or replicate information stored within a protected IC.
Recovery projects may involve preserving programmable logic data, archived program files, binary configuration images, heximal programming files, embedded firmware, associated software, internal memory resources, or engineering documentation maintained alongside the original project. Similar engineering requirements are commonly found in projects involving ALTERA Chip devices, other CPLD platforms, and legacy programmable logic families. Recovering these valuable engineering assets allows organizations to preserve design continuity while supporting maintenance, product migration, and long-term lifecycle management of critical electronic systems.

The demand for programmable logic recovery continues to increase because many industrial installations still rely on obselete or outdate electronic platforms that remain operational despite discontinued component availability. Manufacturing equipment, transportation systems, laboratory instruments, communication infrastructure, and process automation controllers often cannot be replaced without significant financial investment.
When original source code, project file, production software, archived firmware, or configuration data are unavailable, organizations face extended downtime and costly redevelopment efforts. Recovering flash contents where applicable, preserving eeprom parameters, organizing binary archives, reconstructing heximal files, and maintaining engineering program documentation provide valuable support for equipment refurbishment and modernization. These engineering resources enable companies to replicate, duplicate, restore, modify, and maintain legacy hardware while minimizing production interruptions and preserving compatibility with existing installations.

Description
The ispLSI 1016 is a High-Density Programmable Logic Device containing 96 Registers, 32 Universal I/O pins, four Dedicated Input pins, three Dedicated Clock Input pins and a Global Routing Pool (GRP). The GRP provides complete interconnectivity between all of these elements. The ispLSI 1016 features 5-Volt in-system programming and in-system diagnostic capabilities. It is the first device which offers non-volatile reprogrammability of the logic, as well as the interconnect to provide truly reconfigurable systems.
The basic unit of logic on the ispLSI 1016 device is the Generic Logic Block (GLB). The GLBs are labeled A0, A1 .. B7 (see figure 1). There are a total of 16 GLBs in the ispLSI 1016 device. Each GLB has 18 inputs, a programmable AND/OR/XOR array, and four outputs which can be configured to be either combinatorial or registered. Inputs to the GLB come from the GRP and dedicated inputs. All of the GLB outputs are brought back into the GRP so that they can be connected to the inputs of any other GLB on the device from BREAK IC.
