Reset on Brown-out
A Brown-out is a condition where device power (V
DD
)
dips below its minimum value, but not to zero, and then
recovers. The device should be reset in the event of a
Brown-out.
To reset PIC10F220/222 devices when a Brown-out
occurs, external Brown-out protection circuits may be
built, as shown in Figure 8-7 and Figure 8-8.

Power-down Mode (Sleep)
A device may be powered down (Sleep) and later
powered up (wake-up from Sleep).
8.9.1
SLEEP
The Power-Down mode is entered by executing a
SLEEP
instruction.
If enabled, the Watchdog Timer will be cleared but
keeps running, the TO bit (STATUS<4>) is set, the PD
bit (STATUS<3>) is cleared and the oscillator driver is
turned off. The I/O ports maintain the status they had
before the
SLEEP
instruction was executed (driving
high, driving low or high-impedance).
For lowest current consumption while powered down,
the T0CKI input should be at V
DD
or V
SS
and the GP3/
MCLR/V
PP
pin must be at a logic high level if MCLR is
enabled.
Note
1:
This circuit will activate Reset when V
DD
goes
below Vz + 0.7V (where Vz = Zener voltage).
Pin must be configured as MCLR.

Note 1:
This Brown-out Protection circuit employs
Microchip Technology’s MCP809 micro-
controller supervisor. There are 7 different
trip point selections to accommodate 5V to
3V systems.
Pin must be configured as MCLR.
