With on-chip V
are truly stand-alone System-on-a-Chip solutions. All analog and digital peripherals are enabled/disabled
and configured by user firmware. The Flash memory can be reprogrammed even in-circuit, providing non-
volatile data storage, and also allowing field upgrades of the 8051 firmware.
On-board JTAG debug circuitry allows non-intrusive (uses no on-chip resources), full speed, in-circuit
debugging using the production MCU installed in the final application. This debug system supports inspec-
tion and modification of memory and registers, setting breakpoints, watchpoints, single stepping, run and
halt commands. All analog and digital peripherals are fully functional while debugging using JTAG.
Each MCU is specified for operation over the industrial temperature range (–45 to +85 °C). The Port I/O,
RST, and JTAG pins are tolerant for input signals up to 5 V. The devices are available in 100-pin TQFP or
64-pin TQFP packaging. Table 1.1 lists the specific device features and package offerings for each part
number. Figure 1.1 through Figure 1.6 show functional block diagrams for each device.
