Introduction
MAX® devices programmable logic devices (PLDs), based Altera® Multiple Array MatriX (MAX) architecture that supports IEEE Std. 1149.1 Joint Test Action Group (JTAG) interface. devices also in-system programmable, which adds programming flexibility provides benefits many phases product development, manufacturing, field use. This application note provides background information in-system programmability (ISP) IEEE Std. 1149.1 JTAG interface discusses advantages using ISP-capable devices. In-system design, prototyping, manufacturing, reduces cost, shortens development time, provides wider range programming options than standard device programming methods. With ISP, can:
Features Benefits
Program reprogram devices after they soldered onto printed circuit board (PCB), minimizing possibility lead damage electrostatic discharge (ESD) exposure. Manufacture systems before finalize device configuration. Perform boundary-scan test (BST) procedures program devices using in-circuit testers. Upgrade systems field after they have been shipped.

Benefits
Devices programmed with VCC-level Eliminates need 12.0-V programming voltage. programming voltage possibility accidental damage lower voltage parts. Also reduces system power requirements. Devices programmed while soldered PCB. Prototype systems assembled before device configuration finalized. Minimizes device handling, thereby protecting devices from lead damage. Cuts prototype development time saves development costs. Simplifies manufacturing, saves time, protects devices from lead damage.
System manufacturing PLDs treated same other board-level devices because they programmed after assembled. implemented using IEEE Std. 1149.1 (JTAG) interface; therefore, circuit testing device programming combined into single manufacturing step using standard in-circuit tester. Programming data downloaded from in-circuit testers, PCs, workstations during final test. Devices programmed with test configurations. In-field programming
Enhances design debugging boardlevel testing capabilities.
Devices reprogrammed field. Adds versatility reduces service costs, thereby making products more attractive consumer.
VCC-Level Programming
ISP-capable devices support through VCC-level programming voltage. devices generate 12.0-V programming voltage internally program, verify, erase device's EEPROM cells, eliminating need external 12.0-V programming voltage typically required programming. ISP-capable devices guaranteed erase programming cycles with 100% programming functional yields.
