DESCRIPTION
The MB89960 series is a single-chip microcontroller that utilizes the F
2
MC-8L core for low voltage and high speed
performance. The microcontroller contains a range of peripheral functions including timers, a serial interface, I
2
C
interface, A/D converter, and external interrupts. The internal I
2
C interface complies with the SM bus standard
and supports an SM bus battery controller.

External interrupts
External interrupt 1 (3 channels)
Three independent interrupt inputs can be used to recover from low-power consumption modes (with edge-
detection function)
External interrupt 2 (1 channel with 8 inputs)
Eight inputs can be used to recover from low-power consumption modes (with "L" level detection function)
Low-power consumption modes (standby modes)
Stop mode (As all oscillations halt in sub-clock mode, current consumption falls to almost zero.)
Sleep mode (The CPU stops to reduce the current consumption to approximately 1/3 of normal.)
Clock mode (All operation halts other than the clock prescaler resulting in very low power consumption.)

DIFFERENCES AMONG PRODUCTS
1.
Memory Space
Please take note of the differences among products before testing and developing software for the MB89960
series.
The RAM and ROM configurations differ among products.
If the bottom stack address is set at the top RAM address, this will need to be relocated if changing to a different
product.
2.
Current Consumption
In the case of the MB89PV960, add the current consumed by the EPROM which is connected to the top socket.
When operated at low speed, one-time PROM and EPROM products will consume more current than mask
ROM products. However, the current consumption in sleep/stop modes is the same.

Mask Options
Functions that can be selected as options and the methods used to specify these options vary by the product.
