80C32E
Description
The 80C32E is a radiation tolerant ROMless version of the 80C52 single chip 8-bit
microcontroller.
The 80C32E retains all the features of the 80C32 with 256 bytes of internal RAM, a 6-
source, 2-level interrupt system, an on-chip oscillator and three 16-bit timer/counters.
The fully static design of the 80C32E reduces system power consumption by bringing
the clock frequency down to any value, even DC, without loss of data.
The 80C32E has 2 software-selectable modes of reduced activity for further reduction
in power consumption. In the idle mode the CPU is frozen while the timers, the serial
port and the interrupt system are still operating. In the power-down mode the RAM is
saved and all other functions are inoperative.

Type Name and Function
O (I)
Address Latch Enable: Output pulse for latching the low byte of the
address during an access to external memory. In normal operation, ALE
is emitted at a constant rate of 1/6 the oscillator frequency, and can be
used for external timing or clocking. Note that one ALE pulse is skipped
during each access to external data memory.
Program Store ENable: The read strobe to external program memory.
When executing code from the external program memory, PSEN is
O activated twice each machine cycle, except that two PSEN activations
are skipped during each access to external data memory. PSEN is not
activated during fetches from internal program memory.
I
External Access Enable: EA must be externally held low to enable the
device to fetch code from external program memory locations.
I
Crystal 1: Input to the inverting oscillator amplifier and input to the
internal clock generator circuits.
O Crystal 2: Output from the inverting oscillator amplifier

Exit from power-down by either reset or external interrupt does not affect the internal
RAM content.
Note:
If idle mode is activated with power-down mode (IDL and PD bits set), the exit sequence
is unchanged, when execution is vectored to interrupt, PD and IDL bits are cleared and
idle mode is not entered.
