GE DS200PTBAG1B Electronic module of gas turbine

Atmel AT29C256 devices will work as ROM memory in the control modules designed to use ROMs. Note, however, that none of the PROM-based control modules support write control of the flash memory. Also note that this memory device is not pin compatible with the AT29C257 used in the flash memory-based control modules. The TP/FT-10F and TP/XF-78F Flash Control Modules have a 10MHz input clock and require an Atmel AT29C257-90J (32K), AT29C517-90J (64K total, 56K usable, 8K unusable), or AT29C010A-90J (128K total, 56K usable, 72K unusable) flash memory with tDS²35ns. The Neuron Chip firmware must be aware of the flash memory sector size to properly support write operations. The AT29C257 has a 64 byte sector size while the AT29C512, and AT29C010A devices have a 128 byte sector size. Using the large memory devices as an alternate part for the AT29C256 requires the generation of a new exported image built with a device definition which contains the correct sector size.

Memory Considerations

 The developer must supply a 32 pin PLCC packaged memory device for the exported application image. The TP/XF-78, TP/FT-10, TP/XF-1250, and TP-RS485 modules support read-only access to external memory. The access time requirement for the memory device depends on the control module. The standard TP/XF-78, TP/FT-10, and TP-RS485 Control Modules have a 5MHz input clock and require a memory access time of 200ns or faster. The TP/XF-1250 Control Module has a 10MHz input clock and requires a memory access time of 90 or 120ns or faster depending on the production date of the module. TP/XF-1250 modules produced on or before January, 1995, (revision code A to G) require a 90ns access time or faster. TP/XF-1250 modules produced on or after February 1, 1995, (revision code H or higher) require a 120ns access time or faster. Table 8 shows the vendor part numbers for 32 Kbyte, PLCC OTP ROMs that fit the socket on the control module. Please note that LCC devices that support UV erasures are not physically compatible with the PLCC socket.

Application Program Development and Export 

Application programs are initially developed, tested, and debugged using the LonBuilder Developer’s Workbench or the NodeBuilder Development tool. See the LonBuilder User’s Guide and NodeBuilder User’s Guide for detailed instructions on developing and testing applications. Refer to the section below which applies to your development platform. Emulation Technology, Inc. sells an adapter (part number ET 322801K600-YAM) to support programming PLCC devices using standard 600 mil DIP PROM programmers.
