Product Overview
The XMOS XS1-L01A-TQ128 is a powerful device that provides a simple design
process and highly-flexible solution to many applications. The device consists
of a single xCORE Tile, which comprises a flexible multicore microcontroller
with tightly integrated I/O and on-chip memory. The processor runs mutiple
tasks simultaneously using logical cores, each of which is guaranteed a slice of
processing power and can execute computational code, control software and I/O
interfaces. Logical cores use channels to exchange data within a tile or across tiles.
Multiple devices can be deployed and connected using an integrated switching
network, enabling more resources to be added to a design. The I/O pins are
driven using intelligent ports that can serialize data, interpret strobe signals and
wait for scheduled times or events, making the device ideal for real-time control
applications.
The device can be configured using a set of software components that are rapidly
customized and composed. XMOS provides source code libraries for many standard
components. The device can be programmed using high-level languages such as
C/C++ and XMOS-originated extensions to C, called XC, that simplify the control
over concurrency, I/O and time.
The XMOS toolchain includes compilers, a simulator, debugger and static timing
analyzer. The combination of real-time software, a compiler and timing analyzer
enables the programmer to close timings on components of the design without a
detailed understanding of the hardware characteristics.
5.1
Logical cores, Synchronizers and Locks
The xCORE Tile has up to eight active logical cores, which issue instructions down
a shared four-stage pipeline. Instructions from the active cores are issued roundrobin. If up to four logical cores are active, each core is allocated a quarter of the
processing cycles. If more than four logical cores are active, each core is allocated
at least 1/n cycles (for n cores). Figure 1 shows the guaranteed core performance
depending on the number of cores used.

There is no way that the performance of a logical core can be reduced below these
predicted levels. Because cores may be delayed on I/O, however, their unused
processing cycles can be taken by other cores. This means that for more than
four logical cores, the performance of each core is often higher than the predicted
minimum.

Channel Ends, Links and Switch
Logical cores communicate using point-to-point connections formed between two
channel ends. Between tiles, channel communications are implemented over
xConnect Links and routed through switches. The links operate in either 2bit/direction or 5bit/direction mode, depending on the amount of bandwidth required.
Circuit switched, streaming and packet switched data can both be supported efficiently. Streams provide the fastest possible data rates between xCORE Tiles (up to
250 MBit/s), but each stream requires a single link to be reserved between switches
on two tiles. All packet communications can be multiplexed onto a single link. A
total of four 5bit links are available between both cores.
Information on the supported routing topologies that can be used to connect
multiple devices together can be found in the XS1-L Link Performance and Design
Guide, X2999.
5.3
Ports and Clock Blocks
Ports provide an interface between the logical cores and I/O pins. All pins of a port
provide either output or input. Signals in different directions cannot be mapped
onto the same port.
The operation of each port is synchronized to a clock block. A clock block can be
connected to an external clock input, or it can be run from the divided reference
clock. A clock block can also output its signal to a pin. On reset, each port is
connected to clock block 0, which runs from the xCORE Tile reference clock.
The ports and links are multiplexed, allowing the pins to be configured for use by
ports of different widths or links. If an xConnect Link is enabled, the pins of the
underlying ports are disabled. If a port is enabled, it overrules ports with higher
widths that share the same pins. The pins on the wider port that are not shared
remain available for use when the narrower port is enabled. Ports always operate
at their specified width, even if they share pins with another port.
5.4
Timers
Timers are 32-bit counters that are relative to the xCORE Tile reference clock. A
timer is defined to tick every 10 ns. This value is derived from the reference clock,
which is configured to tick at 100 MHz by default.
5.5
PLL
The PLL creates a high-speed clock that is used for the switch, tile, and reference
clock. The PLL multiplication value is selected through the two MODE pins, and
can be changed by software to speed up the tile or use less power. The MODE pins
are set as shown in Figure 2:
Figure 2 also lists the values of OD, F and R, which are the registers that define
the ratio of the tile frequency to the oscillator frequency:

The MODE pins must be held at a static value until the third rising edge of the
system clock following the deassertion of the system reset.
For 500 MHz parts, once booted, the PLL must be reprogrammed to provide this
tile frequency. The XMOS tools perform this operation by default.
Further details on configuring the clock can be found in the XS1-L Clock Frequency
Control document, X1433.
5.6
Boot ROM
The xCORE Tile boot procedure is illustrated in Figure 3. In normal usage,
MODE[3:2] controls the boot source according to the table in Figure 4. If bit
5 of the security register (see §5.7.1) is set, the device boots from OTP.

5.7
OTP
The xCORE Tile integrates 8 KB one-time programmable (OTP) memory along with
a security register that configures system wide security features. The OTP holds
data in 2k rows x 32-bit configuration which can be used to implement secure
bootloaders and store encryption keys. Data for the security register is loaded
from the OTP on power up. All additional data in OTP is copied from the OTP to
SRAM and executed first on the processor.
5.7.1
Security Register
The security register enables the following security features:
· Secure Boot: The xCORE Tile is forced to boot from address 0 of the OTP,
allowing the xCORE Tile boot ROM to be bypassed (see §5.6). This feature can
be used to implement a secure bootloader which loads an encrypted image from
external flash, decrypts and CRC checks it with the processor, and discontinues
the boot process if the decryption or CRC check fails. XMOS provides a default
secure bootloader that can be written to the OTP along with secret decryption
keys.
· Disable JTAG: The JTAG interface is disabled, making it impossible for the tile
state or memory content to be accessed via the JTAG interface.
· Disable Link access: Other tiles are forbidden access to the processor state via
the system switch.
Disabling both JTAG and Link access transforms an xCORE Tile into a “secure
island” with other tiles free for non-secure user application code.
· Disable Global Debug access: Disables access to the DEBUG_N pin.
X1154,
XS1-L01A-TQ128 Datasheet
11
· OTP Master and Sector Lock: Further access to the OTP is prevented by setting
the master lock. Locks can also be applied to each of the four OTP sectors
individually.
These security features provide a strong level of protection and are sufficient for
providing strong IP security.
5.8
SRAM
The xCORE Tile integrates a single 64 KB SRAM bank for both instructions and
data. All internal memory is 32 bits wide, and instructions are either 16-bit or
32-bit. Byte (8-bit), half-word (16-bit) or word (32-bit) accesses are supported and
are executed within one tile clock cycle. There is no dedicated external memory
interface, although data memory can be expanded through appropriate use of the
ports.
5.9
JTAG
The JTAG module can be used for loading programs, boundary scan testing, incircuit source-level debugging and programming the OTP memory.

Figure 5:

TRST_N
DEBUG_N
The JTAG chain structure is illustrated in Figure 5. Directly after reset, two TAP
controllers are present in the JTAG chain: the boundary scan TAP and the chip TAP.
The boundary scan TAP is a standard 1149.1 compliant TAP that can be used for
boundary scan of the I/O pins. The chip TAP provides access into the xCORE Tile,
switch and OTP for loading code and debugging.
The TRST_N pin must be asserted low during and after power up for 100 ns. If JTAG
is not required, the TRST_N pin can be tied to ground to hold the JTAG module in
reset.
The DEBUG_N pin is used to synchronize the debugging of multiple xCORE Tiles.
This pin can operate in both output and input mode. In output mode and when
configured to do so, DEBUG_N is driven low by the device when the processor hits
a debug break point. Prior to this point the pin will be tri-stated. In input mode
and when configured to do so, driving this pin low will put the xCORE Tile into
debug mode. Software can set the behavior of the xCORE Tile based on this pin.

This pin should have an external pull up of 4K7-47K Ω or left not connected in
single core applications.

PCU
The PCU can be used to isolate the core voltage of the device and reapply it under
a controlled condition known as sleep mode. In sleep mode, all data in the SRAM is
lost. The device recovers into functional mode under the control of an external
PCU_WAKE signal or an internal timer.
If the PCU is not required, PCU_WAKE should be left unconnected, PCU_GATE
should be left unconnected and PCU_CLK must be tied to CLK.
5.11
Power Supplies
The device has the following types of power supply pins:
· VDD pins for the xCORE Tile tile
· VDDIO pins for the I/O lines
· PLL_AVDD pins for the PLL
· PCU_VDD and PCU_VDDIO pins for the PCU
· OTP_VCC pins for the OTP
· OTP_VPP pins for faster programming the OTP (optional)
Several pins of each type are provided to minimize the effect of inductance within
the package, all of which must be connected. The power supplies must be brought
up monotonically and input voltages must not exceed specification at any time.
The VDD supply must ramp from 0 V to its final value within 10 ms to ensure
correct startup.
X1154,
XS1-L01A-TQ128 Datasheet
13
The VDDIO supply must ramp to its final value before VDD reaches 0.4 V.
The PLL_AVDD supply should be separated from the other noisier supplies on
the board. The PLL requires a very clean power supply, and a low pass filter (for
example, a 4.7 Ω resistor and 100 nF multi-layer ceramic capacitor) is recommended
on this pin.
The PCU_VDD supply must be connected to the VDD supply.
The PCU_VDDIO supply must be connected to the VDDIO supply.
The OTP_VCC supply should be connected to the VDDIO supply.
The OTP_VPP supply can be optionally provided for faster OTP programming times,
otherwise an internal charge pump is used.
The following ground pins are provided:
· PLL_AGND for PLL_AVDD
· GND for all other supplies
All ground pins must be connected directly to the board ground.
The VDD and VDDIO supplies should be decoupled close to the chip by several
100 nF low inductance multi-layer ceramic capacitors between the supplies and
GND (for example, 4x100nF 0402 low inductance MLCCs per supply rail). The
ground side of the decoupling capacitors should have as short a path back to the
GND pins as possible. A bulk decoupling capacitor of at least 10 uF should be
placed on each of these supplies.
RST_N is an active-low asynchronous-assertion global reset signal. Following a
reset, the PLL re-establishes lock after which the device boots up according to the
boot mode (see §5.6). RST_N and must be asserted low during and after power up
for 100 ns.

The input valid window parameter relates to the capability of the device to capture

sum of the input setup time and input hold time with respect to the external clock
as measured at the pins. The output invalid window specifies the time for which
an output is invalid with respect to the external clock. Note that these parameters
are specified as a window rather than absolute numbers since the device provides
functionality to delay the incoming clock with respect to the incoming data.

Development Tools
XMOS provides a comprehensive suite of development tools. Source files, timing
scripts and a board design file are input to the compiler toolchain which produces
a binary executable. This executable file can be simulated, loaded onto the device
and debugged over JTAG, programmed into flash memory on the board or written
to OTP memory on the device. The tools can also encrypt the flash image and write
the decrpytion key securely to OTP memory.
The tools can be driven from either a graphical development environment or the
command line and are supported on Windows, Linux and MacOS X. The tools are
available at no cost from xmos.com/downloads. Information on using the tools is
provided in a separate user guide, X1013.

Device Errata
This section describes minor operational differences from the data sheet and
recommended workarounds. As device and documentation issues become known,
this section will be updated the document revised.
To guarantee a logic low is seen on the pins RST_N, DEBUG_N, MODE[3:0], TRST_N,
TMS, TCK and TDI, the driving circuit should present an impedance of less than
100 Ω to ground. Usually this is not a problem for CMOS drivers driving single
inputs. If one or more of these inputs are placed in parallel, however, additional
logic buffers may be required to guarantee correct operation.
For static inputs tied high or low, the relevant input pin should be tied directly to
GND or VDDIO.
