What makes
What makes
• 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
