Product specification
OM5926HN
1 FEATURES
Subscriber Identification Module (SIM) card interface in
accordance with GSM11.11, GSM11.12 (Global System
for Mobile communication) and ISO 7816 requirements
VCC regulation (3 or 5 V ±8%) with controlled rise and
fall times
www.DataSheet4OUn.ceopmrotected and buffered pseudo-bidirectional I/O line
(I/O referenced to VCC and SIMI/O referenced to VDDI)
Clock generation (up to 10 MHz) with synchronous start
and frequency quadrupling
Clock stop LOW, clock stop HIGH or 1.25 MHz (from
internal oscillator) for cards Power-down mode
Automatic activation and deactivation sequences of an
independent sequencer
Automatic processing of pin RST with the counting of
the 41928 CLK cycles for the beginning of the
Answer-To-Reset (ATR)
Warm reset command
Supply voltage supervisor for power-on reset, spike
killing and emergency deactivation in case of supply
drop-out
DC-to-DC converter (doubler, tripler or follower)
allowing operation in a 3 or 5 V environment
(2.5 VDD 6 V)
Enhanced Electrostatic Discharge (ESD) protection on
card side (6 kV minimum)
Power-down mode with several active features and
current reduction
Off mode with 5 µA current
Control from a microcontroller via a 400 kHz slave
I2C-bus (address 48H)
Interface signals supplied by an independent voltage
(1.5 VDDI 6 V).
2 APPLICATIONS
GSM mobile phones.
3 GENERAL DESCRIPTION
The OM5926HN is a low cost one chip SIM interface, in
accordance with GSM11.11, GSM11.12 with card current
limitation. Controlled by the I2C-bus, it is optimized in
terms of board space, external components count and
connection count (see Chapter 13).
Due to the integrated DC-to-DC converter, the device
ensures full cross-compatibility between 3 or 5 V cards
and 3 or 5 V environments. The very low power
consumption in Power-down mode and Off mode saves
battery power.
