PSD3XX Family
For a complete product comparison, refer to Table 1.
PSD3XX references the standard version of the PSD3XX family, which are ideal for
general-purpose embedded control applications.
PSD3XXR SRAM-less version of the PSD3XX. If you don’t require the 16 Kb SRAM or
need a larger external SRAM, go with this part to save cost.
ZPSD3XX has improved technology that helps reduce current consumption using the Turbo
bit. Excellent if you require a 5 V version of the PSD3XX that uses less power.
ZPSD3XXR SRAM-less version of the ZPSD3XX.
ZPSD3XXV 2.7 V to 5.5 V operation, ideal for very low-power and low-voltage
applications.
ZPSD3XXRV SRAM-less version of the ZPSD3XXV.
Throughout this data sheet, references are made to the PSD3XX. In most cases, these
references also cover the entire family. Exceptions will be noted. References, such as
“3X1 only” cover all parts that have a 301 or 311 in the part number. Use the following table
to determine what references cover which product versions:
The PSD3XX I/O ports can be used for:
