Data Classification
Maximum Ratings
Maximum ratings are absolute ratings; exceeding only one of these values may cause irreversible
damage to the integrated circuit.
Characteristics
The listed characteristics are ensured over the operating range of the integrated circuit. Typical
characteristics specify mean values expected over the production spread. If not otherwise specified,
typical characteristics apply at TA = 25 °C and the given supply voltage.
Operating Range
In the operating range the functions given in the circuit description are fulfilled.
For detailed technical information about “Processing Guidelines” and “Quality Assurance” for
ICs, see our “Short Form Catalog”.

The resulting delay of SDA-output data is the sum of the open drain stage plus the time
determined by the bus capacitance and the external pullup resistor or the impedance of the
internal open drain pulldown transistor respectively.
I2CEN = 0
Wait condition
To force the M3L-master to interrupt the transmission sequence until MEGATEXT is ready for
more data, MEGATEXT can force down SCL after the transmission of a complete byte. At that
time the bus master has to switch its SCL-output to high impedance and check the state of SCL
afterwards.During SCL check I2CEN has to be low.

The center frequency of the MEGATEXT horizontal PLL is proportional to the crystal frequency. In PAL-mode the
centre frequency is 15.625 kHz for the typical crystal frequency of 20.48 MHz. Deviations from the typical crystal
frequency will shift the range of the horizontal frequencies where the PLL is able to lock.

Reset/Chip Initialization
A power-on reset or a reset pulse at pin RES lead to a hardware reset and a software initialization
of registers and internal DRAM. During initialization bus transfers are not allowed.
At / after power-on a reset pulse at pin RES is necessary. RES may return to 0 after the supply
voltage reached its lower limit for chip function (4.7 V). This may be achieved by a capacitor C
between RES and VDD and by a resistor R between RES and VSS. The dimensions of R and C
depend on the worst case rise time of VDD.
Initialization time after power- tINIT
on or falling edge of RES
25
ms
VDD greater 4.7 V
If the supply voltage drops below VDD min, the IC has to be reset by pin RES.
Pulse width RES
100
ns
High level at pin RES causes chip reset.
In rare cases, the IC may remain in a permanent reset state after power up, depending on the
applicational context. After power up, the software should check proper operation. In case the
Megatext does not react properly, power supply should be switched off for at least 3 s. After that,
power supply can be switched on again.
