UPSD3212C Datasheet, PDF (119/152 Pages) STMicroelectronics – Flash Programmable System Devices with 8032 Microcontroller Core and 16Kbit SRAM

UPSD3212C, UPSD3212CV
AC/DC PARAMETERS
These tables describe the AD and DC parameters
of the uPSD321X Devices:
§ DC Electrical Specification
§ AC Timing Specification
s PLD Timing
– Combinatorial Timing
– Synchronous Clock Mode
– Asynchronous Clock Mode
– Input Macrocell Timing
s MCU Module Timing
– READ Timing
– WRITE Timing
– Power-down and RESET Timing
The following are issues concerning the parame-
ters presented:
– In the DC specification the supply current is giv-
en for different modes of operation.
– The AC power component gives the PLD, Flash
memory, and SRAM mA/MHz specification. Fig-
ure 62 and Figure 63 show the PLD mA/MHz as
a function of the number of Product Terms (PT)
used.
– In the PLD timing parameters, add the required
delay when Turbo Bit is '0.'
