device numbering conventions

Figure 17 illustrates the numbering and symbol nomenclature for the TMS370Cx6x family.

370

6 7

Prefix: TMS = Standard prefix for fully qualified devices

SE = System evaluator (window EPROM) that is used for

prototyping purpose.

Family:

370 = TMS370 8-Bit Microcontroller Family

Technology:

C = CMOS

Program Memory Types:

0 = Mask ROM

7 = EPROM

Device Type:

6 = x6x device containing the following modules:

– Timer 1

– Timer 2A

– Timer 2B

– Serial Peripheral Interface

– Serial Communications Interface (SCI1)

– Analog-to-Digital Converter (ADC1)

Memory Size:

7 = 24K Bytes

8 = 32K Bytes

9 = 48K Bytes

Temperature Ranges:

A = – 40

°C

T= – 40

°C to 105°C

Packages:

FN = Plastic Leaded Chip Carrier

FZ = Ceramic Leaded Chip Carrier

ROM and EPROM Option:

A = For ROM device, the watchdog timer can be configured

as one of the three different mask options:

– A standard watchdog

– A hard watchdog

– A simple watchdog

The clock can be either:

– Divide-by-4 clock

– Divide-by-1 (PLL) clock

The low-power modes can be either:

– Enabled

– Disabled

A = For EPROM device, a standard watchdog, a divide-by-

4 clock, and low-power modes are enabled
