Product specification
8-bit microcontrollers with DTMF
generator and 256 bytes EEPROM
PCA3354C; PCD3354A
Notes to the DC characteristics
1.
TONE output; EEPROM erase and write require V
DD
≥
2.5 V:
a) TONE output requires f
xtal
< 4 MHz in case DIV3 = 0.
b) TONE output requires f
xtal
< 12 MHz in case DIV3 = 1.

; all other outputs open:
a) Maximum values: external clock at XTAL1 and XTAL2 open-circuit.
b) Typical values: T

4.
Values are specified for DTMF frequencies only (CEPT).
5.
Related to the Low Group Frequency (LGF) component (CEPT).
6.
After final testing the value of each EEPROM bit is typically logic 1.
7.
Verified on sampling basis.
8.
V
POR
is an option chosen by the user. Depending on its value, it may restrict the supply voltage range.
9.
Each device is tested on the condition: V

< V
POR
; to ensure a correct start-up, even for slow rising supply
voltages.
