1. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

PIN DESCRIPTION
WEN0,
1, 2
WEN0B
I
LVDS Write Enable 0. When WEN0 > WEN0B, the result is a logic 1 in the write current selection. Otherwise it is
logic 0.
WEN1,
3, 4
WEN1B
I
LVDS Write Enable 1. When WEN1 > WEN1B, the result is a logic 1 in the write current selection. Otherwise it is
logic 0.
WEN2,
5, 6
WEN2B
I LVDS Write Enable 2. When WEN2 > WEN2B, the result is a logic 1 in the write current selection. Otherwise it is
logic 0.
BSEL
7
I Digital Bank Select input selects the write current register banks.
RFREQ
8
I/O Analog A resistor from RFREQ to GND sets the range of the HFM frequency.
IAPC
9
I Analog A 1k impedance current input; 100*IAPC flows to the output. This controls the read current, which may
also include a current from an internal DAC.
VSL
10
O Power The internal 2.5V regulator; a 1µF capacitor from VSL to GND is recommended. Do not use VSL for other
loads.
GND 11, 16, 20
Ground Ground
RSET
12
I/O Analog A resistor from RSET to analog ground sets the DAC full-scale current.
