Introduction
Lattice is the inventor and the leader in the (ISP) In-System Programming PLD technology. One of the visions and
ultimate goal of ISP is the live field upgrade of a mission critical system. Being a mission critical system, the field
upgrade process must meet the following criteria.
With the introduction of the LatticeXP2 Flash based non-volatile FPGA family, Lattice deliver the first and only ISP
products with all the critical attributes required to provide the ultimate solution of ISP, reliable and secure live field
upgrade of a mission critical system. The critical attributes are:
The block diagram of the LatticeXP2 device shown in Figure 17-1 provides a bird’s eye view for the unique co-exis-
tence of the Master SPI port with the Slave SPI port. The detail of the LatticeXP2 Slave SPI interface can be found
in the document dedicated on the subject. TransFR, the must have feature for the mission critical field upgrade, is
available only on the JTAG port. Therefore, the programming activities described in this document will focus on the
JTAG port only.

1. It must be extremely reliable as any form of programming failure is not acceptable.
2. The system must remain functional throughout as even a small interruption is not acceptable including
3. Various security features will be required to protect the IP (Intellectual Property) of the mission critical sys-
1. Dual boot feature and Flash Protect to provide the extremely reliable system.
2. Instant-on, Background Programming, and TransFR features provide seamless live field upgrade.
3. Key Protect and Encryption to protect users’ Intellectual Property.
