4 / 61 page TMS370Cx2x 8-BIT MICROCONTROLLER SPNS018C – FEBRUARY 1993 – REVISED FEBRUARY 1997 4 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251–1443 description The TMS370C020A, TMS370C022A, TMS370C320A, TMS370C322A, TMS370C722, and SE370C722 devices are members of the TMS370 family of single-chip 8-bit microcontrollers. Unless otherwise noted, the term TMS370Cx2x refers to these devices. The TMS370 family provides cost-effective real-time system control through integration of advanced peripheral modules and various function on-chip memory configurations. The TMS370Cx2x family uses high-performance silicon-gate CMOS EPROM and EEPROM technology. Low operating power, wide operating temperature range, and noise immunity of CMOS technology coupled with the high performance and extensive on-chip peripheral functions make the TMS370Cx2x devices attractive in system designs for automotive electronics, industrial motor, computer peripheral controls, telecommunications, and consumer applications. All TMS370Cx2x devices contain the following on-chip peripheral modules: D Serial peripheral interface (SPI) D Serial communications interface 1 (SCI1) D One 24-bit general-purpose watchdog (WD) timer D One 16-bit general-purpose timer with an 8-bit prescaler Table 1 lists memory configurations of the TMS370Cx2x devices.

The mechanical drawing of the NJ is identical to the N2 package and did not need to be requalified. The suffix letter A appended to the device names in Table 1 indicates the configuration of the devices. ROM or EPROM devices have different configurations as indicated in Table 2. ROM devices with the suffix letter A are configured through a programmable contact during manufacture. |
