The MAX3320 combines a microprocessor (µP) super-

visory circuit with an RS-232 transceiver. The power-on

reset performs a single function: it asserts a reset signal

♦ Precise Monitoring of 5V and 3.3V Power-

Supply Voltages:

— 100ms (min) Power-On RESET Pulse Width

— Power-Supply Transient Immunity

whenever the V supply voltage declines below a pre-

set threshold, staying asserted for at least 100ms after

— Guaranteed RESET Valid to V = 1V

rises above the reset threshold. The MAX3320 has

an active-low RESET output, which is guaranteed to be in

the correct state for V down to 1V. The reset compara-

♦ Power-On Reset Always Active

♦ 4µA Low-Power Shutdown

♦ 250kbps Guaranteed Data Rate

The MAX3320 tra nsc e ive rs ha ve a p roprie ta ry low-

dropout transmitter output stage, enabling true RS-232

performance with a dual charge pump powered from a

+3V to +5.5V supply. The device requires only four

small 0.1µF external charge-pump capacitors, and is

guaranteed to run at data rates of up to 250kbps. It

comes in the space-saving 20-pin SSOP package.
