What makes
What makes µ µPSD 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

www.st.com/micropsd
•Built-in Address Decoding PLD
– Map any µPSD memory sector to any address
– Easily convert existing 8051 designs into µPSD
– Total memory mapping flexibility for new designs
•Memory Paging is Easy using Decode PLD
– Break traditional 8051 64K Byte address limit imposed by only 16 address lines
– 8-bit page register is built into Decode PLD … it’s like having 8 more address lines
– Paging (or banking) is directly supported by most 8051 C compilers

•8051 Architecture uses a separate address space for code and for data
•Allocate dual banks of Flash to meet Application Demands
– The Decode PLD controls where Flash memory resides
•You decide how to split the Flash memory

•8051s typically cannot write to “code” space
– Special µPSD register eliminates this limitation
•Typical Flash memory cannot be read and written
at the same time
– Dual Banks of Flash eliminate this limitation
– Read program from one bank while writing to the other bank
Remote Field Updates with IAP
Remote Field Updates with IAP
3. After IAP
2. During IAP
1. Before IAP
• Special Register temporarily re-
classifies Main Flash as Data
• MCU now reads IAP program
from 2nd Flash while receiving
bytes of new program from
USB, UART, Modem, I2C, etc.
and writes the new program to
Main Flash
• Special Register classifies
Main Flash as Code again
• MCU now reading new
program from Main Flash
• MCU reading program
from Main Flash
