POR circuit (i.e., release RESET). A maximum rise
time for V
When the device starts normal operation (exits the
RESET condition), device operating parameters
(voltage, frequency, temperature) must be met to
ensure proper operation.

The Power-up Timer provides a 72 ms nominal time-
out on power-up, keeping the device in RESET and
allowing V
The power-up time delay will vary from chip-to-chip due
to V

1.4
The MCP23016 uses an external RC circuit to
determine the internal clock speed. The user must
connect R and C to the MCP23016, as shown in
Figure 1-1.

Internal Clock
A 1 MHz (typ.) internal clock is needed for the device to
function properly. The internal clock can be measured
on the TP pin. Recommended R
are shown in Table 1-2.

This block manages the functionality of the I
interface and protocol handling. The MCP23016
supports the following commands:

The last three LSb of the 7-bit address are user-defined
(see Table 1-4). Three hardware pins (<A2:A0>) define
these bits.
