Mitsubishi Electronics America's Electronic Device Group has announced the sample availability of the M37516, an 8 bit smart battery microcontroller that has 32 kbytes of on-chip flash memory to enable in-circuit flash reprogramming, a SMBus (system management bus) interface that enables communication with other SMBus compatible Smart Battery System (SBS) devices, a 10 bit ADC for precise battery charging/discharging control, and peripheral functions in a package small enough squeeze into battery packs.
The company says that operating on a single, 5 V power supply, the microcontroller's on-chip Flash memory supports parallel, serial, and CPU programming modes, and allows users to control programming and erase functions via software commands. Also, the device's SMBus interface can be used as an I2C interface using software switching. The device conforms to SM0Bus 1.1 specifications.
The M37516 smart battery flash microcontroller is specifically designed for smart battery systems for portable applications that use the industry- standard SMBus serial communication protocol. The M37516 microcontroller connects with Mitsubishi's keyboard controller (M38867 or M38869) and smart battery charger/selector IC (M62255) via the two-wire, serially configured SMBus to make a complete smart battery system.
The M37516, which normally draws 34 mW of power, is designed to reduce smart battery system power consumption in several ways. Its built-in clock generation circuit operates via a ceramic resonator or quartz crystal oscillator. The device features 2,7-5,5 V operation at a 4 MHz oscillation frequency and 4,0-5,5 V operation at an 8 MHz oscillation frequency. It has a 32 kHz secondary clock source and power-down modes. The 'wait' power-down mode stops the internal clock but not the external oscillator so the system draws 25% of the normal operating current; the 'stop' power-down mode stops both the internal clock and external oscillator, drawing only 40 µA of current.
Key features: Flash memory - 32 kbytes; RAM - 1024 bytes; Serial I/O - 8 bit x 1 (UART or clock synchronised) and 8 bit x 1 (clock synchronised); Multimaster I2C bus interface circuit; four 8 bit timers; pulse width modulation - 8 bit x 1; A/D converter - 10 bit x 8 channel; watchdog timer - 16 bit x 1 channel; Two clock generator circuits (32 kHz and 8 MHz).
