STFPC320集成電路（IC）的電源管理-專用規(guī)格書PDF中文資料

STFPC320屬于集成電路（IC）的電源管理-專用。由意法半導(dǎo)體集團制造生產(chǎn)的STFPC320電源管理 - 專用專用型電源管理集成電路 (PMIC) 用于電源的控制或操作，適合特定或小范圍的目標(biāo)應(yīng)用，例如汽車氣囊管理、電容器組平衡、AC 公共電力監(jiān)控、存儲器總線端接、接地故障檢測、能量收集、小型引擎管理、處理器或芯片集專用電壓調(diào)節(jié)、負載突降保護、觸覺驅(qū)動器、熱電制冷器控制等。

Description

The STFPC320 is designed to integrate the VFD driving, key-scan matrix, LED driving, infrared (IR) remote control decoding and real-time clock (RTC) into one integrated solution. All the functions are programmable using the I2C bus.

Features

■ IC front panel VFD controller driver

■ Standby power management to the host

■ 3.3 V (VDD) and down to -30 V (VSS) supply for the IC

■ IR remote control decoder (Philips, NEC, Thomson, Sony, Matsushita)

■ Multiple display modes (12 seg. and 16 digits to 20 seg and 8 digits)

■ High voltage outputs (VDD - 33.3 V max)

■ No additional external resistors required for driver outputs (P-CH. open drain + pull-down resistor outputs)

■ Key scanning (up to 12 x 2 matrix = 24 keys)

■ LED ports (4 channels 20 mA max each)

■ Serial I2C interface (SCL, SDA) communication protocol b

■ Operating speed: up to 400 kHz for I2C

■ Programmable hotkeys for IR remote control command and KEYSCAN command

■ Low power consumption in standby mode

■ Dimming circuit (8 steps)

■ Real-time clock (accuracy ± 25 secs/month)

■ Wake-up alarm

■ Internal oscillator with external crystal for RTC

■ Available in PQFP-52 package (0.65 mm pitch

Applications

■ VCR, DVD and personal video recorders

■ Home theatre with clock feature, STB and HTiB (home theater in a box)
