SN8P2501 使用注意事項 V1.0SN8P2501 使用注意事項 適用對象 : 客戶或代理商 SN8P2501 為 SONIX 新開發的 14 pin、1T (one clock per machine cycle) 8-bit MCU,內建 16MHz RC 震盪器, 最多有 12 I/O 可用,並具備優異的抗雜訊能力。在系統開發階段,軟、硬體注意事項請參考下文敘述,開發軟件 請用 “ SN8IDE V1.99I ” 或之後版本。(註:包裝正印 SN8PEV2501 為工程樣品,程式宣告一樣為 CHIP SN8P2501)。 1 CODEOPTION : Code OptionContentFunction Description Low cost RC for external high clock oscillator and XOUT becomes to general Ext_RC purpose I/O (P1.2). Low frequency, power saving crystal (e.g. 32.768KHz) for external high clock 32K_X’tal oscillator. 12M_X’tal High speed crystal /resonator (e.g. 12MHz) for external high clock oscillator. High_Clk 4M_X’tal Standard crystal /resonator (e.g. 3.58M) for external high clock oscillator. Internal high RC 16MHz and external oscillator pins as general purpose I/O (XIN IHRC_16M to P1.3, XOUT to P1.2). Internal high RC 16MHz with RTC function and external oscillator pins connect IHRC_RTC with 32.768KHz crystal to generating real time clock. Enable Enable noise filter to enhance noise immunity performance. Noise_Filter Disable Disable noise filter. Always_On Watchdog timer always on. Watch_Dog Disable Disable Watchdog function. Fosc/1 Instruction cycle is oscillator clock. Fosc/2 Instruction cycle is 2 oscillator clocks. Fosc/4 Instruction cycle is 4 oscillator clocks. Fcpu Fosc/8 Instruction cycle is 8 oscillator clocks. Fosc/16 Instruction cycle is 16 oscillator clocks. http://www.DataSheet4U.net/ Fosc/32 Instruction cycle is 32 oscillator clocks. Fosc/64 Instruction cycle is 64 oscillator clocks. -2MHz Internal high RC 16MHz typical frequency - 2MHz. -1MHz Internal high RC 16MHz typical frequency -1MHz. 16M_IHRC Normal Internal high RC 16MHz typical frequency. +1MHz Internal high RC 16MHz typical frequency + 1MHz. +2MHz Internal high RC 16MHz typical frequency + 2MHz. Reset Enable External reset pin. Reset_Pin Disable External reset pin and the pin is as input only pin P1.1 without pull-up P11 resister. Enable Enable ROM code Security function. Security Disable Disable ROM code Security function. Enable Enable Low Power function to save Operating current. Low Power Disable Normal. 本資料為松翰科技股份有限公司專有之財產,非經書面許可不准透露或使用本資料,亦不准複印複製或轉變成任何其他形式使用。 The information contained herein is the exclusive property of SONiX technology Co., Ltd. and shall not be distributed , reproduced , or disclosed in whole or in part without prior written permission of SONiX technology Co., Ltd.
