LC87F7932B中文资料8-bit LCD Driver Microcontroller with 32K-byte Flash ROM and 2048-byte RAM数据手册ONSEMI规格书

描述 Description

The LC87F7932B is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 250 ns, integrates a number of hardware features such as 32K-byte flash ROM (on-board programmable), 2048-byte RAM, an on-chip debugger, an LCD controller/driver, sophisticated 16-bit timer/counter (may be divided into 8-bit timers), a 16-bit timer/counter (may be divided into 8-bit timers/counters or 8-bit PWMs), four 8-bit timers with a prescaler, a real time clock function (RTC), a synchronous SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO interface, a full duplex UART interface, a 12-bit/8-bit 7-channel A-D converter, a high speed clock counter, a system clock frequency divider, a power-on reset function and a 21 source, 10 vector interrupt feature.

• Minimum bus cycle time is 250 ns (4.0 MHz) at VDD = 2.4 to 3.6 V
• Minimum instruction cycle time is 750 ns (4 MHz) at VDD = 2.4 to 3.6 V

简介

LC87F7932B属于集成电路（IC）的微控制器。由制造生产的LC87F7932B微控制器微控制器产品是相对复杂的用户可编程数字逻辑器件。这些产品与视为微控制器的器件密切相关，两者之间的区别主要体现在制造商选择的用词。不过按照传统，微控制器集成了工作存储器，也更可能包含混合信号外设，并且往往与更简单的软件范例结合使用，旨在重复执行一系列预定义的任务。
