General Description
The devices 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 HT6220A/HT6221A/HT6221B/HT6222A contain 30keys (K1~K20, K33~K34, K37~K38, K41~K42, 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 triggered, the programmed address/data is transmitted together with the header bits via an IR (38kHz carrier) transmission medium.

HT6220A/HT6221A/HT6221B/HT6222A
Functional Description
Keyboard Scan 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 keyboard 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 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 inverse 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 simultaneous 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. The HT6221A/HT6221B/HT6222A also provide three double-key active functions (K21+K22, K21+K23, and K21+K24) for tape deck recording operations. The double-key operation rules are shown in timing 4 and timing 6. Transmission Codes The transmission codes of the devices consist of a 9ms header code, a 4.5ms off code, 16-bit address codes (18ms~36ms), 9ms~18ms 8-bit data codes, and the inverse code of the 8-bit data codes. The following is an illustration of the transmission codes.

Timing 3. Logic States
* 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 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 inversion are decided by Logical OR between the external switch S8~S15 and the ROM2. For example: The following is an illustration of these rules in selecting the address codes (A0~A15).

Valid Double-Key Input DOUT and IR LED 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. IRC The frequency of the internal RC(IRC) oscillator is depending on the temperature and operating voltage. At Ta=25C at 3.0V, the IRC has an accuracy of 1 per cent. In the range of 0C to 70C at 2.0V~3.6V, the accuracy value of the RC frequency increases to the maximum value of 2 per cent.
