Features
General Description
• The PT8A992P works as the encoder and the
PT8A993P works as the decoder
The PT8A992P/993P is a pair of CMOS LSIs designed
for remote controlled toy car application. They have 11
control keys for controlling the corresponding motion (i.e.
forward, backward, left, right and 7 other functions) of
the remote controlled car.
• 11 output pins, 4 for forward, backward, left and
right functions, and 7 functional keys
• Operation power supply: 3.0V to 5.5V
• Auto power-off if no key pressed within 2s
(PT8A992P)
• Auto shut-down if keep pressing a key for more
than 4 minutes (PT8A992P)
• Auto shut down if no signal input for more than 5
minute (PT8A993P)
• Low operating current
• On-chip oscillator with an external resistor
• On-chip receiving amplifiers
• Few external components needed

Coding Method
Functional Description
Each trigger pin is triggered by corresponding bit of data in
format of “1”. The data string is 18-bit and divided to four
segments, i.e., Start Code, Data Code, Parity Code and End
code, where
For PT8A992P, a PC pin is used to control on or off of external
power supply. When pressing any key, the PC output pin will
keeps on a high level. If none of keys is pressed within 2 sec-
onds, the PT8A992 will shut down automatically and no level
output on the PC pin. On the other hand, if any of keys is kept
pressed for 4 minutes, the PT8A992P will also shut down to
save battery power.
Start Code = 11110.
Data Code = F3 F4 F B F5 R L F1 F6 F7 F2
F = Forward
R = Right
F2 = Function 2
B = Backward
L = Left
F3 = Function 3
F5 = Function 5
F1= Function 1
F4 = Function 4
The PT8A993P also features Auto Power Off function when
no any signal received within 5 minutes. Two over-current pro-
tection pins VT1 and VT2 are used for current limit in accor-
dance with the toy safety standard HD271. They act to shut
down the output level if the input voltage keeps more than
0.095VCC for 3 seconds.
F6 = Function 6
F7 = Function 7
Parity Code = Even parity check result
End Code is for data latch.
Data code can be any combination of F, B, F5, R, L, F1, F2,
F3, F4, F6 and F7 except F&B and R&L.
