The PSD4000 family of ultra low-power programmable system devices (PSDs) provide 100% in-system, programmable concurrent flash memory, SRAM, programmable logic, and extra I/O for 16- and 32-bit microcontrollers from vendors such as Motorola, Intel, Hitachi, Infineon, and Philips, as well as DSPs from Texas Instruments and Analog Devices.
Two devices have been introduced, with the PSD4135G2 and PDS4235G2 offering 512 KB of flash, a second concurrent 32-KB flash array, 8 KB of SRAM, a configurable interface for 16- and 32-bit MCUs and DSPs, a programmable address decoder, a small CPLD, combinatorial logic, and configurable pin assignments. The devices also have an ISP JTAG port that allows production line, in-system programming in less than 20s per device. The PSD4235G2 also allows JTAG chaining during in-system programming and has additional sequential logic in a 3000-gate, general-purpose CPLD.
New devices will be added this year and next that expand the flash memory to eight and sixteen bits. Pricing for the PSD4135G2 is $8.35 each/10,000 and the PSD4235G2 is $9.75 each/10,000.
