GreenPAK Programmable Mixed-Signal Matrix

with Dual 44 m

Ω/2 A P-FET

take maximal 450 us for ACMP0/1 and a shorter time for ACMP2/3. The short wake mode can be used to reduce the current

consumption.

To use any ACMP under WS controller, the following settings must be done:



ACMP Power Up Input from matrix = 1 (for each ACMP separately);



CNT/DLY0 must be set to Wake and Sleep Controller function (for all ACMP);



CNT/DLY0 set/reset input = 0 (for all ACMP).

The user can select a period of time while the ACMP is sleeping in a range of 1 - 65535 clock cycles. Before they are sent to

sleep their outputs are latched so the ACMPs remain their state (High or Low) while sleeping.

WS controller has the following settings:



Wake and Sleep Output State (High/Low)

If OSC is powered off (Power-down option is selected; Power-down input = 1) and Wake and Sleep Output State = High, the

ACMP is continuously on.

If OSC is powered off (Power-down option is selected; Power-down input = 1) and Wake and Sleep Output State = Low, the

ACMP is continuously off.

Both cases WS function is turned off.



Counter Data (Range: 1 - 65535)

User can select wake and sleep ratio of the ACMP; counter data = sleep time, one clock = wake time.



Q mode - defines the state of WS counter data when Set/Reset signal appears Reset - when active signal appears, the WS

counter will reset to zero and High level signal on its output will turn on the ACMPs. When Reset signal goes out, the WS

counter will go Low and turn off the ACMP until the counter counts up to the end. Set - when active signal appears, the WS

counter will stop and Low level signal on its output will turn off the ACMP. When Set signal goes out, the WS counter will go on

counting and High level signal will turn on the ACMP while counter is counting up to the end.

Note: The OSC0 matrix power-down to control ACMP WS is not supported for short wait time option.



Edge Select defines the edge for Q mode

High level Set/Reset - switches mode Set/Reset when level is High

Note: Q mode operates only in case of "High Level Set/Reset”.



Wake time selection - time required for wake signal to turn the ACMPxH on

Normal Wake Time - when WS signal is High, it takes BG/analog start up time to turn the ACMPs on. They will stay on until

WS signal is Low again. Wake time is one clock period. It should be longer than BG turn on time and minimal required com-

paring time of the ACMP.

Short Wake Time - when WS signal is High, it takes BG/analog start up time to turn the ACMPs on. They will stay on for 1 µs

and turn off regardless of WS signal. The WS signal width does not matter.



Keep - pauses counting while Keep = 1



Up - reverses counting

If Up = 1, CNT is counting up from user selected value to 65535.

If Up = 0, CNT is counting down from user selected value to 0.
