Overview
The STM706RAM6F is a microprocessor supervisor IC produced by STMicroelectronics. It belongs to the STM70x family of supervisors, which are self-contained devices designed to provide essential supervisory functions for microprocessors. These devices monitor the VCC input for out-of-tolerance conditions and assert a reset signal when such conditions occur. The STM706RAM6F is available in an 8-pin SOIC package and is suitable for industrial applications due to its operating temperature range of -40°C to 85°C.

Q & A
- What is the primary function of the STM706RAM6F?
The primary function of the STM706RAM6F is to provide microprocessor supervisory functions, including monitoring the VCC input for out-of-tolerance conditions and asserting a reset signal when necessary.
- What are the reset threshold voltages for the STM706RAM6F?
The reset threshold voltage for the STM706RAM6F is 2.63 V (typ.).
- What is the typical reset timeout period for the STM706RAM6F?
The typical reset timeout period is 200 ms.
- Does the STM706RAM6F have a watchdog timer?
Yes, the STM706RAM6F includes a 1.6 s (typ.) watchdog timer to detect out-of-control MCU conditions.
- How does the manual reset input work on the STM706RAM6F?
The manual reset input (MR) asserts the reset output when it is driven low. The reset remains asserted as long as MR is low and for the reset timeout period after MR returns high.
- What is the purpose of the power-fail comparator in the STM706RAM6F?
The power-fail comparator provides an early warning of impending power failure by comparing an external voltage to an internal reference voltage.
- What is the typical supply current of the STM706RAM6F?
The typical supply current is 40 μA.
- What is the operating temperature range of the STM706RAM6F?
The operating temperature range is -40°C to 85°C.
- Is the STM706RAM6F RoHS compliant?
Yes, the STM706RAM6F is RoHS compliant with an Ecopack3 rating.
- In what package types is the STM706RAM6F available?
The STM706RAM6F is available in an 8-pin SOIC package.
