General Description
The devices are CMOS LSI encoders designed for use
in remote control systems. They are capable of encod-
ing 16-bit address codes and 8-bit data codes. Each ad-
dress/data input can be set to one of the two logic
states, 0 and 1.
K45~K46, K49~K50), 32 keys (K1~K32), 48 keys
(K1~K32, K33~K34, K37~K38, K41~K42, K45~K46,
K49~K50, K53~K54, K57~K58, K61~K62) and 64 keys
(K1~K64), respectively. When one of the keys is trig-
gered, the programmed address/data is transmitted to-
gether with the header bits via an IR (38kHz carrier)
transmission medium.
The HT6220A/HT6221A/HT6221B/HT6222A contain
30keys (K1~K20, K33~K34, K37~K38, K41~K42,

The HT6222A keyboard form
The devices remain in the halt mode during the standby
state (at this time, the oscillator stops, and the standby
current<1mA). The HT6220A consists of 30 active keys,
HT6221A has 32 active keys, HT6221B has 48 active
keys, and the HT6222A has 64 active keys. The key-
board forms of the devices are shown below.

When one of the keys (30, 32, 48 or 64 keys) is triggered
for over 36ms, the oscillator is enabled and the chip is acti-
vated. 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 ad-
dress 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
pressed key is held for 108ms, if the key is still held down,
the transmission codes turn out to be a composition of
header (9ms) and off codes (2.24ms) only.

To avoid mistakes made by keyboard scanning or simul-
taneous two-key inputs (except for the three double-key
active functions (K21+K22, K21+K23, and K21+K24),
the devices are facilitated with 36ms starting time.

ble-key operation rules are shown in timing 4 and timing
6.

Setting the address codes (A0~A15)
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.
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
both ²00H². The A0~A7 are set by logical OR between

Values of the data codes (D0~D7)
Table 3: Double-key data code table
The HT6220A/HT6221A/HT6221B/HT6222A contain
30, 32, 48 and 64 active keys, respectively. Each key
corresponds to a data code. For tape deck recording,
the HT6221A/HT6221B/HT6222A provide three dou-
ble-key functions. The double-key, single-key, and
double-key operation rules are shown in Table 3, Ta-
ble 4, Timing 4, Timing 5 and Timing 6.

Timing 6. Valid Double-Key Input
DOUT and IR LED
IRC
After the transmission codes are sent, the DOUT pin
generates transmission codes with a carrier, and the
IR-LED goes low to drive a transmission indicator. The
DOUT pin abbreviate exterior transistor, to provide large
current driving ability.
The frequency of the internal RC(IRC) oscillator is de-
pending on the temperature and operating voltage.
At Ta=25°C at 3.0V, the IRC has an accuracy of ±1 per
cent. In the range of 0°C to 70°C at 2.0V~3.6V, the accu-
racy value of the RC frequency increases to the maxi-
mum value of ±2 per cent.
