描述 Description

A monitoring and protection circuit for 3- and 4-cell Li-ion applications that require the highest safety, including safe authentication, low cost, and high utilization of the cell energy. The microcontroller includes 32 KB self-programming Flash program memory, 2 KB SRAM, 1024B EEPROM, 2, 3 or 4 cells in series, over-current, high-current, and short-circuit protection, 12-bit voltage A/D converter, 18-bit coulomb counter-current A/D converter, and debugWire interface for on-chip debug.The device features autonomous battery protection during charging and discharging and supports very accurate accumulated current measurements using an 18-bit A/D converter with a resolution of 0.84 μV. It also supports up to eight MIPS throughput at 8 MHz, 4-25V operation.

簡介

ATmega32HVB屬于集成電路（IC）的微控制器。由制造生產的ATmega32HVB微控制器微控制器產品是相對復雜的用戶可編程數(shù)字邏輯器件。這些產品與視為微控制器的器件密切相關，兩者之間的區(qū)別主要體現(xiàn)在制造商選擇的用詞。不過按照傳統(tǒng)，微控制器集成了工作存儲器，也更可能包含混合信號外設，并且往往與更簡單的軟件范例結合使用，旨在重復執(zhí)行一系列預定義的任務。
