16 LED drivers. Each output programmable at:
16 output channels can sink up to 100 mA, tolerate up to 40 V when OFF
5 MHz Ultra Fast-mode unidirectional interface (write only)
256-step (8-bit) linear programmable brightness per LED output varying from fully off
(default) to maximum brightness using a 31.25 kHz PWM signal
256-step group brightness control allows general dimming (using a 122 Hz PWM
signal) from fully off to maximum brightness (default)
256-step group blinking with frequency programmable from 15 Hz to 16.8 s and duty
cycle from 0 % to 99.6 %
Output state change programmable on the Acknowledge (this ninth bit is always set
to 1 by UFm I
or all at the same time (default to ‘Change on STOP’).
Five hardware address pins allow 32 PCU9655 devices to be connected to the same
UFM bus and to be individually programmed
Four software programmable I
three LED Sub Call addresses) allow groups of devices to be addressed at the same
time in any combination (for example, one register used for ‘All Call’ so that all the
PCU9655s on the UFm bus can be addressed at the same time and the second
register used for three different addresses so that
addressed at the same time in a group). Software enable and disable for each
programmable UFm bus address.
Unique power-up default Sub Call address allows mixing of devices with different
channel widths
Software Reset feature (SWRST Call) allows the device to be reset through the
UFm bus
8 MHz internal oscillator requires no external components
Internal power-on reset
Noise filter on USDA/USCL inputs
Glitch free LED outputs on power-up
Thermal shutdown with thermal protection
Operating power supply voltage (V
5.5 V tolerant inputs on non-LED pins
40 C to +85 C operation
ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per
JESD22-C101
Latch-up testing is done to JEDEC Standard JESD78 Class II, Level B
