供应台湾松瀚单片机SN8P2604A
信息内容：SN8P2604A 8位微控制器具有高性能,低功耗的特點.指令執行時間為1個時鐘震盪週期的結構使工作速度可達16MIPS。高EFT能力使SN8P2604A適合在高干擾環境下工作。SN8P2604A的IC結構設計一流,包括一個大容量（4K-word）的程式記憶體（OTP ROM），128-byte的資料記憶體(RAM),兩個8位定時/計數器(T0.TC1)，一個看門狗計時器，四個中斷源(T0, TC1, INT0, INT1)，以及8層堆疊緩存區。此外，用戶可自行選擇晶片的振盪形式,有四種不同的外部振盪結構提供給系統作為時鐘源：高/低速晶體振盪器/陶瓷諧振器和RC振盪器等。SN8P2604A還可以通過程式設定內部RC振盪器作為低速模式時鐘源 (function() {if (typeof desc === 'undefined') {setTimeout(arguments.callee, 100);return;} TShop.renderDesc(desc);})();
供应义隆单片机EM78P468N
信息内容：The EM78P468N/L is an 8-bit microprocessor designed and developed with low-power and high-speed CMOStechnology. Integrated onto a single chip are on chip Watchdog Timer (WDT), Data RAM, ROM, programmable real timeclock counter, internal/external interrupt, power down mode, LCD driver, infrared transmitter function, and tri-state I/O.The series has an on-chip 4K×13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). TheEM78P468L provides multi-protection bits to prevent intrusion of user’s OTP memory code. Seven Code option bits areavailable to meet user’s requirements. Special 13 bits customer ID options are provided as well.With its enhanced OTP-ROM feature, the EM78P468N/L provides a convenient way of developing and verifying user’sprograms. Moreover, this OTP device offers the advantages of easy and effective program updates, using developmentand programming tools. User can avail of the ELAN Writer to easily program his development code.
