1 Product Description
The TPMC917 is a standard single-width 32 bit PMC module providing 4 Mbyte SRAM with battery
backup by an on board lithium cell for all SRAM devises and four ESD protected RS232 channels
(TPMC917-10 only).
The 4 Mbyte NV-SRAM is organized in two banks, each of them provides 512k x 32 bit memory.
During normal operation (standard 5V supply applied to the SRAM) the capacity of the lithium cell is
monitored every 24 hours by the battery monitor device and an interrupt can be generated, if the
battery voltage is too low. The monitor device switches the power supply of the SRAM from the
standard 5V to the battery if the 5V supply drops below the threshold level of the battery monitor
device. Any active access to the SRAM at this point is executed correctly within 1.5µs. After this time
any further accesses to the SRAM are not possible. A miniature DIP switch allows the selection of the
battery backup source either from the on board lithium cell or from an external battery via the P14 I/O
connector.
The TPMC917-10 provides four RS232 channels. Each channel has a programmable baud rate up to
115.2 Kbaud. The 4 channel UART16C654 provides 64 byte transmit FIFO and 64 byte receive FIFO
for each channel to significantly reduce the overhead required to provide data to and get data from the
transmitter and receiver. The FIFO trigger levels are programmable. The channels are ESD protected
up to +/-15kV according to the human body model and IEC1000-4-2.
For applications which do not need the UARTs of the TPMC917-10, the TPMC917-20 provides
4 MByte NV-SRAM and has no UARTs.
The TPMC917-21 has a reduced memory size. It provides 2 MByte NV-SRAM and has no UARTs.

3.3.2 Special Registers
The TMPC917 provides two special registers. For fast status detection there is a FIFO Status Register
for channel 0 to channel 3, and an Interrupt Status Register for all four channels and the battery
interrupts.
For TPMC917-20/21, only the battery interrupt bits of the Interrupt Status Register carry valid data.

3.3.2.1 FIFO Ready Register Channel 0-3 (TPMC917-10 only)
The FIFO Ready Register FIFORDY1 is a byte wide read only register. The FIFO Ready Register
provides the status of the transmit and receive FIFOs of channel 0 to channel 3. Each TX and RX
channel (0-3) has its own 64 byte FIFO. If any of the TX/RX FIFOs become empty/full, the status bit
associated with the TX/RX function of channel 0-3 is set in the FIFO Ready Register.
For TPMC917-20/21, this register carries random data.

3.3.2.2 Interrupt Status Register
The Interrupt Status Register is a byte wide read / write register located in the PCI Memory Space
(PCI Base Address 3 + 0x21) and is useful for fast interrupt source detection.
It reflects the interrupt status of the four UART channels and the two Battery Status Interrupts.
The battery interrupts can be enabled and disabled.

If the “PCI Interrupt Enable” of the PCI target chip is disabled
(Interrupt Control/Status Register bit 6 is set to ‘0’). This register
can be used as a polling register for interrupts of the four serial
controllers.
Interrupts from the four serial channels can be individual
enabled by the ST16C654 serial controller. After reset all UART
interrupts are disabled.
For TPMC917-20/21, these bits carry random data.

4.1.2 PCI Base Address Initialization
PCI Base Address Initialization is scope of the PCI host software.
PCI9030 PCI Base Address Initialization:
1. Write 0xFFFF_FFFF to the PCI9030 PCI Base Address Register.
2. Read back the PCI9030 PCI Base Address Register.
3. For PCI Base Address Registers 0:5, check bit 0 for PCI Address Space.
Bit 0 = '0' requires PCI Memory Space mapping
Bit 0 = '1' requires PCI I/O Space mapping
For the PCI Expansion ROM Base Address Register, check bit 0 for usage.
Bit 0 = ‘0’: Expansion ROM not used
Bit 0 = ‘1’: Expansion ROM used
4. For PCI I/O Space mapping, starting at bit location 2, the first bit set determines the size of the
required PCI I/O Space size.
For PCI Memory Space mapping, starting at bit location 4, the first bit set to '1' determines the size
of the required PCI Memory Space size.
For PCI Expansion ROM mapping, starting at bit location 11, the first bit set to '1' determines the
required PCI Expansion ROM size.
For example, if bit 5 of a PCI Base Address Register is detected as the first bit set to ‘1’, the
PCI9030 is requesting a 32 byte space (address bits 4:0 are not part of base address decoding).
5. Determine the base address and write the base address to the PCI9030 PCI Base Address
Register. For PCI Memory Space mapping the mapped address region must comply with the
definition of bits 3:1 of the PCI9030 PCI Base Address Register.
After programming the PCI9030 PCI Base Address Registers, the software must enable the
PCI9030 for PCI I/O and/or PCI Memory Space access in the PCI9030 PCI Command Register
(Offset 0x04). To enable PCI I/O Space access to the PCI9030, set bit 0 to '1'. To enable PCI
Memory Space access to the PCI9030, set bit 1 to '1'.

4.4 Local Software Reset
The PCI9030 Local Reset Output LRESETo# is used to reset the on board local logic.
The PCI9030 local reset is active during PCI reset or if the PCI Adapter Software Reset bit is set in the
PCI9030 local configuration register CNTRL (offset 0x50).
CNTRL[30] PCI Adapter Software Reset:
Value of ‘1’ resets the PCI9030 and issues a reset to the Local Bus (LRESETo# asserted). The
PCI9030 remains in this reset condition until the PCI Host clears this bit. The contents of the PCI9030
PCI and Local Configuration Registers are not reset. The PCI9030 PCI Interface is not reset.

The local interrupt 1 reflects the four channel UART interrupts (TPMC917-10 only). Bit 2 will be set if
bit 1 is set and an interrupt is generated on one or more UART channels. For more information see
chapter “Interrupt Status Register”.
The local interrupt 2 reflects the status of the backup battery supply voltage (either on board Lithium
Cell or external battery via P14 mezzanine connector). This register will be initialized from the on
board EEPROM after power-on the TPMC917 with the above shown initial values.

6 Installation
6.1 Security Warning (Lithium Battery)
CAUTION! - This system contains a lithium battery. Lithium batteries may explode if
mishandled.
Please observe the following warnings strictly. If misused, the battery may explode or leak,
causing injury or damage to the equipment.
• Keep batteries out of the reach of children. In case of ingestion of a cell or battery, the person
involved should seek medical assistance promptly.
• The batteries must be inserted into the equipment with the correct polarity (+ and -).
• Do not use metallic or other conductive extraction tools to replace the batteries.
• Do not attempt to revive used batteries by heating, charging or other means.
• Do not dispose of batteries in fire. Do not dismantle batteries.
• Do not short circuit batteries.
• Do not expose batteries to high temperatures, moisture or direct sunlight.
• Do not place batteries on a conductive surface (anti-static work mat, packaging bag or form trays)
as it can cause the battery to short.
CAUTION !
The battery may explode if it is incorrectly replaced. Replace only with the same or equivalent
type recommended by the manufacturer. Dispose of used batteries according to the
manufacturer's instructions.

6.2 Battery Backup Selection
The TPMC917 provides two possibilities for battery backup operation: either the on board Lithium Cell
or an external battery connected via the P14 I/O connector. An original packed Lithium Cell is
delivered together with the TPMC917. Insert the Lithium Cell with the plus pole “+” visible. A four
position miniature DIP switch is used to select the source for battery backup. Factory configuration is
switched S3, S4 in position “ON” and S1, S2 in position “OFF” to provide battery backup by the on
board Lithium Cell. Switching S3, S4 to the “OFF” position and S1, S2 to the “ON” position enables an
external battery connected via the P14 I/O connector as battery backup source.
Figure 6-1 : DIP switch position
Following figures show the DIP switch configurations:
Figure 6-2 : DIP switch settings for Battery Backup by on board Lithium Cell (factory configuration)
TPMC917 User Manual Issue 1.0.7 Page 24 of 26
Figure 6-3 : DIP switch settings for battery backup via P14 I/O Connector
Figure 6-4 : DIP switch settings for battery backup disabled
Any other DIP switch settings are not allowed.
If the voltage of the backup battery is lower than the specified battery fault voltage, an interrupt will be
issued to the PCI bus during normal operation (TPMC917 powered by standard 5V supply). In that
case all memory data should be saved on another non-volatile memory medium, the TPMC917 should
be switched off and the battery has to be changed.
To use the interrupt based battery monitor function of the TPMC917 the interrupts must be
enabled in the Interrupt Control/Status Register (INTCSR) of the PCI target chip (default after
EEPROM download). The battery interrupts must also be enabled in the Interrupt Status
Register.
Insert the Lithium Cell with the plus pole “+” visible.
During battery operation no battery test will be executed to save battery power. It is
recommended to power-up the module, at the latest after the specified data retention time, to
check battery status.
The specified data retention depends on the ambient operating temperature. A higher ambient
temperature as specified may lead to a significantly shorter data retention time.
