Preliminary Speciﬁcation

MB96300

FME/EMDC- 2007-02-12

MB96300_shortspec.fm

Real Time Clock

MB96F348H/T: no

others: 1

Can be clocked either from sub oscillator (devices with partnumber sufﬁx “W”), main oscillator or from

the RC oscillator

Facility to correct oscillation deviation of Sub clock or RC oscillator clock (clock calibration)

Read/write accessible second/minute/ hour registers

Can signal interrupts every halfsecond/second/ minute/hour/day

Internal clock divider and prescaler provide exact 1s clock based on a 4 MHz or a 32 kHz clock input

(devices with partnumber sufﬁx “W”)

Virtually all external pins can be used as general purpose I/O

All push-pull outputs (except when used as I2C SDA/SCL line)

Bit-wise programmable input enable

Bit-wise programmable Pull-up resistor

Bit-wise programmable as input/output or peripheral signal

Bit-wise programmable as CMOS schmitt trigger/ automotive / TTL input

Bit-wise programmable output driving strength

Alarm comparator

2 channels

MB96384R/Y,

MB96385R/Y:

1 channel

others:

2 channels

Monitors an external voltage and generates an interrupt in case of a voltage lower or higher than the

deﬁned thresholds

Threshold voltages deﬁned externally or generated internally

Status is readable, interrupts can be masked separately

External bus

interface

Yes

Multiplexed address/data lines

Non-multiplexed address/data lines (MB96V300 and MB9638x only)

16-bit bidirectional data bus

24-bit address lines (MB9635x: 22-bit address lines)

Wait state request

External bus master possible

Timing programmable

Chip select

6 signals

Clock output

function

2 channels

Output any on-chip clock

Inverted and non-inverted clock (MB9636x,MB9635x has only non-inverted clock output)

Prescaler: 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 of selected clock

Synchronous or asynchronous start/stop

Low voltage reset

Reset is generated when supply voltage is below minimum.
