合泰红外线遥控器IC HT6220A

盛群推出 HT6220A/HT6221A/HT6222A 高整合度的红外线遥控器IC

11/19/2009

盛群半导体针对红外线遥控器IC HT622x系列进行改版，推出高整合度的 HT6220A/HT6221A/HT6222A系列。利用内建OSC电路及红外线LED驱动MOSFET，比传统红外线遥控器IC节省许多的外部零件 -- 1颗455kHz Resonator、2颗电容、1颗晶体管及1颗电阻。在遥控器按键未按下时， HT622xA属于待机状态，此时静态电流小于1uA，可以让电池具备很长的使用寿命。

HT6220A/HT6221A/HT6222A的载波频率为38kHz，采用脉冲位置调制方法，透过红外线LED发码，内含16-bit地址码及8-bit数据码。HT6220A支持30个按键输入，HT6221A支持32个按键输入，HT6222A支持64个按键输入，同时此系列也支持3个"双按键"。

该系列IC广泛的使用于各种应用的遥控器 -- 电视机、机顶盒、DVD播放机、音响、小家电等。出货形式为已测wafer、die封装，封装形式有16NSOP、20SOP、24SOP，其中20SOP与24SOP封装脚位与HT622x相同，PCB不需要变更，即可直接替换。

HT6220A/HT6221A/HT6221B/HT6222A

Multi-Purpose Encoders

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 本型号/HT6221A/HT6221B/HT6222A contain 6keys (K21~K23, K25~K27) or 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.

Operating voltage: 2.0V~3.6V
DOUT with 38kHz carrier for IR medium
Low standby current
Minimum transmission word: one word
Build-in RC (Internal RC) oscillator
