General Description
The HT6221/HT6222 are CMOS LSI encoders designed
for use in remote control systems. They are capable of
encoding 16-bit address codes and 8-bit data codes.
Each address/data input can be set to one of the two logic
states, 0 and 1.
The HT6221/HT6222 contain 32 keys (K1~K32) and 64
keys (K1~K64), respectively. When one of the keys is
triggered, the programmed address/data is transmitted
together with the header bits via an IR (38kHz carrier)
transmission medium.

HT6221/HT6222
Functional Description
Keyboard scan
When one of the keys (32 or 64 keys) is triggered for over
36ms, the oscillator is enabled and the chip is activated. If
the key is pressed and held for 108ms or less, the 108ms
transmission codes are enabled and comprised of a
header code (9ms), an off code (4.5ms), low byte address
codes (9ms~18ms), high byte address codes
(9ms~18ms), 8-bit data codes (9ms~18ms), and the in-
verse codes of the 8-bit data codes (18ms~9ms). After the
The HT6221/HT6222 remain in the halt mode during the
standby state (at this time, the oscillator stops, and the
standby current<1mA). The HT6221 consists of 32 ac-
tive keys, and the HT6222 has 64 active keys. The key-
board forms of the HT6221/ HT6222 are shown below.

Logic states
both "00H". The A0~A7 are set by logical OR between
the external switch S0~S7 and the ROM1. The
A8~A15 equal some bits inverted to A0~A7, the inver-
sion are decided by Logical OR between the external
switch S8~S15 and the ROM2.
·
Setting the address codes (A0~A15)
The algorithm rule of the address codes (A0~A15) can
be selected by mask option.
In this case, the 16-bit on-chip MASK ROM (ROM1
and ROM2) are available, and the value of ROM1 (8
bits) and ROM2 (8 bits) are decided by one MASK
LAYER. The current value of ROM1 and ROM2 are
For example:
The following is an illustration of these rules in selecting
the address codes (A0~A15).

·
Values of the data codes (D0~D7)
Table 3: Double-key data code table
The HT6221/HT6222 contain 32 and 64 active keys,
respectively. Each key corresponds to a data code.
For tape deck recording, the HT6221/HT6222 provide
three double-key functions. The double-key, sin-
gle-key, and double-key operation rules are shown in
Table 3, Table 4, Timing 4, Timing 5 and Timing 6.
