The IEEE 1532 in-system programmability (ISP) standard aims to simplify manufacturing support for ISP devices. The IEEE 1532 specification enables concurrent in-system programming of multiple devices in minimum time. The standard builds on the 1149.1 JTAG boundary-scan architecture standard by addressing both silicon and software issues to create a simplified and homogeneous ISP environment. The standard specifies a common software platform for programming a variety of device types, including memory devices and programmable logic devices (PLDs). It enables common system operation for all IEEE 1532-compliant devices on a system board.
The IEEE 1532 standard is complementary to the JEDEC-approved Jam™ Standard Test and Programming Language (STAPL). The IEEE 1532 standard is a hardware standard that defines the actual ISP algorithm for each device, while Jam STAPL is a software standard that defines the file format that stores the programming information for the chain of devices.
The official IEEE 1532 specification can be obtained from the IEEE Online Catalog & Store.
Altera Supports IEEE 1532 Specification
The first PLD supplier to ship IEEE 1532-compliant devices, Altera was a major participant in the development and approval of the specification and provides complete silicon and software support for the IEEE 1532 programming specification. Table 1 lists the Altera® devices that are IEEE 1532-compliant.
| Table 1. Altera Devices Supporting the IEEE 1532 Specification | ||||
| Devices | IEEE 1532-Compliant Devices | |||
|---|---|---|---|---|
| CPLDs | MAX® II, MAX 7000AE, MAX 7000B, MAX 3000A | |||
| Configuration EPROMs | EPC4, EPC8(1), EPC16 | |||
- EPC8 devices are IEEE 1532-compatible.
