What makes What makes
µ µ PSD PSD
different? different?
• PSD Architecture … enhances capability of 8051
– PSD = Programmable System Device
– Dual bank Flash Memory … Superior IAP
– Memory Management … Seamless paging and memory placement
– Programmable Logic … Consolidate external logic chips
– JTAG ISP … perfect for lab and manufacturing
• Some µPSDs have Big Memory up to 288K bytes…
When is larger Flash and SRAM needed?
– The use of C language
– Elaborate user interfaces … menus, graphics, screens
– Multiple languages and fonts, data tables
– Faster data transfers
– Data recording
• Low Cost
– Save $ compared to other 8051 and 8-bit MCU devices with
larger SRAM and Flash Memories
