XR32330EBERTR-F

MaxLinear · Pre-ordered Chips · QFN-24-EP(4x4)

XR32330EBERTR-F from MaxLinear, in a QFN-24-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 R1IN input ±15kV ESD-protected RS-232 receiver 1 input with internal 5K pull-down (input range ±15V).
2 R2IN input ±15kV ESD-protected RS-232 receiver 2 input with internal 5K pull-down (input range ±15V).
3 R3IN input ±15kV ESD-protected RS-232 receiver 3 input with internal 5K pull-down (input range ±15V).
4 T1OUT output ±15kV ESD-protected RS-232 driver 1 output, short-circuit protected to ground.
5 T2OUT output ±15kV ESD-protected RS-232 driver 2 output, short-circuit protected to ground.
6 T3OUT output ±15kV ESD-protected RS-232 driver 3 output, short-circuit protected to ground.
7 T3IN input TTL/CMOS driver 3 input referenced to VL; connect to GND or VL if unused.
8 T2IN input TTL/CMOS driver 2 input referenced to VL; connect to GND or VL if unused.
9 T1IN input TTL/CMOS driver 1 input referenced to VL; connect to GND or VL if unused.
10 R3OUT output TTL/CMOS receiver 3 output referenced to VL; high-Z in shutdown.
11 R2OUT output TTL/CMOS receiver 2 output referenced to VL; high-Z in shutdown.
12 R1OUT output TTL/CMOS receiver 1 output referenced to VL; high-Z in shutdown.
13 STATUS output TTL/CMOS output that indicates whether valid RS-232 levels are present at R1IN, R2IN or R3IN (low when none).
14 SHUTDOWN input TTL/CMOS input; driven low it shuts down the device (drivers tri-stated, charge pump disabled), high gives normal operation.
15 ONLINE input TTL/CMOS input; low enables Auto On-Line mode, high disables it.
16 C1- passive Negative terminal of the voltage doubler charge pump capacitor (0.1µF for 3.0V to 3.6V VCC).
17 GND power_in Ground.
18 VL power_in Logic I/O supply, 1.65V to 5.5V and not greater than VCC.
19 VCC power_in Power supply, 3.0V to 5.5V.
20 V+ power_out Regulated positive (+5.5V) charge pump rail, needs a storage capacitor.
21 C1+ passive Positive terminal of the voltage doubler charge pump capacitor.
22 C2+ passive Positive terminal of the inverting charge pump capacitor.
23 C2- passive Negative terminal of the inverting charge pump capacitor.
24 V- power_out Regulated negative (-5.5V) charge pump rail, needs a storage capacitor.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
